卫工08 年5月一、嵌入式PLC简介1、开发背景工控系统有大系统和小系统，特别是小系统，范围广，几乎覆盖了全部行业，并且要求是千差万其余。
控制器件有DCS、IPC和PLC等。
广大工控设计人员在器件选型时十分疑惑。
在数据办理上要求像IPC，在靠谱性上要求达到或超出PLC，在价位上力求便宜，好像单片机；在二次开发（应用程序）方面要求语言普通化、易学易懂易掌握。
谁都梦想有一款新式的工控产品能代替、包括IPC、PLC和单片机。
经过艰辛的努力，嵌入式PLC在科威公司问世了。
嵌入式PLC已列入国家科技攻关计划项目的阶段成就。
项目代号为2005BA206C。
2、什么是嵌入式PLC？嵌入式PLC是将通用的PLC梯形图语言、CANbus现场总线协议嵌入到单片机中，使其更具个性化、差别化，应用更宽泛、更灵巧，对用户更方便。

It will ramp down and stop the motor.Figure 9 Data visualizer Stop motor window4.Firmware User ConfigurationAlgorithm can be fine-tuned for any motor by updating motor parameters in “userparams.h” file. Following are the configurations available for the user to modify the motor and algorithm parameters.5.Software ImplementationPWM event generation unit is configured to trigger AFEC module to start adc conversion. Once the trigger is received by AFEC module, two configured phase current measurements are simultaneously sampled and conversion takes place. Phase current result ready event will generate interrupt. Then DC bus voltage is measured inside interrupt. In addition, speed POT is measured if it is enabled.The FOC algorithm is executed inside ADC end of conversion interrupt handler. This interrupt is dedicated for fast controlling and it’s in sync with PWM. If any fast controlling tasks need to be added then this is the place. Apart from this, slow control loop is also available and its frequency can be configured by “SLOW_LOOP_TIME_SEC” in user configurations. Slow loop execution frequency should be in multiple of PWM frequency. Speed ramp and speed PI control loop is executed from slow control loop. If any additional tasks one has to execute at slower rate, then “SlowControlLoop()” function is a place holder.ADCEOCInterruptHandlerRead 2 phase currents Software trigger for DC bus and POTmeasurementClarke Transform Convert balanced three-phase quantities to balanced two-phase quadrature quantitiesPark TransformTwo-phase orthogonal stationary system to orthogonal rotating reference framePLL EstimatorBEMF based PLL observer to Estimate Motor Position and SpeedPI ControllersId(Flux), Iq (Torque) PI controllersInverse Park Transform Rotating reference frame to Orthogonal stationary reference frame Inverse Clarke Transform2 axis orthogonal frame to3 phase stationary frameSVPWMSpace vector modulation to update PWM duty cycleSTOP SlowControlLoopSpeedRamp()PI ControlSpeed PI controlSTOPFigure 10 Control loop flow chart6.ReferencesApp Note - /downloads/en/AppNotes/00002520B.pdfAtmel Studio 7 - /microsite/atmel-studio/Data Visualizer - https:///Products/Details/0b2891f4-167a-49fc-b3f0-b882c7a11f98 7.Revision History。

PI Controller v4.2 User GuideIntroduction (Ask a Question)Proportional Integral (PI) Controller is the widely used closed-loop controller for controlling a first order system. The basic functionality of a PI Controller is to make the feedback measurement track the reference input, which is done by controlling its output till the error between reference and feedback signals becomes zero.Summary (Ask a Question)Features (Ask a Question)PI Controller has the following key features:•Automatic anti-windup and initialization functions are includedImplementation of IP Core in Libero Design Suite (Ask a Question)IP core must be installed to the IP Catalog of the Libero® System-on-Chip (SoC) software. This is done automatically through the IP Catalog update function in the Libero SoC software, or the IP core can be manually downloadedfrom the catalog. Once the IP core is installed in the Libero SoC software IP Catalog, the core can be configured, generated, and instantiated within the SmartDesign tool for inclusion in the Libero project list.Device Utilization and Performance (Ask a Question)The following table lists the device utilization used for PI Controller.Table 1. PI Controller UtilizationImportant: 1.The data in this table is captured using typical synthesis and layout settings. CDR reference clocksource was set to Dedicated with other configurator values unchanged.2.Clock is constrained to 200 MHz while running the timing analysis to achieve the performancenumbers.Table of ContentsIntroduction (1)Summary (1)Features (1)Implementation of IP Core in Libero Design Suite (1)Device Utilization and Performance (1)1.

Functional Description (Ask a Question)This section describes the implementation details of the PI Controller.The following figure shows the block diagram of PI Controller.Figure 1-1. System-Level Block Diagram of PI ControllerThe ref_input_i port connects to the reference input, while the act_input_i port connects to the actual input. Thekp_i and ki_i inputs represent the proportional and integral gains. ymax_i and ymin_i represent the minimum andmaximum outputs. The init_i input represents the initialization value (which is output if the PI Controller is disabled),and the pi_en_i input is used to enable the PI Controller operation. A pulse of one clock cycle width is used tostart the computation. The done_o output signal represents valid data on the output_y_o port. A single clock pulseappears at the done_o signal to represent the end of computation.The entire system is synchronized with the rising edge of clock and controlled by a finite state machine (FSM). The PI Controller block uses a multiply-accumulate-subtract (MAS) block to perform operations like multiplication, addition,and subtraction. There are two components that contribute to the output, the proportional term and the integral term as shown in the following figure. The proportional term is only dependent on the instantaneous value of the errorsignal whereas the integral term is dependent on the present and previous values of error.Figure 1-2. PI Controller in Continuous DomainPI Controller in continuous time domain can be expressed as:where,e(t) = reference(t) - feedback(t) is the error between Reference and feedbacky(t) = PI Controller outputTo implement the PI Controller in digital domain, it has to be discretized. The discretized form of PI Controller based on zero-order hold method is shown in the following figure.Figure 1-3. The Discretized Form of PI ControllerFigure 1-4. Equationwhere,P(n) = Proportional term outputI(n) = Integral term outputI(n-1) = Previous (buffered) value of Integral outputTs = Sampling time in discrete domain1.1 Anti-Windup and Initialization (Ask a Question)The PI Controller has maximum and minimum limits for its output so as to keep it within practical values. If a non-zero error signal persists for a long time, the Integral component of the controller keeps increasing and may reach avalue limited by its bit width. This phenomenon is called integrator windup and has to be avoided to have properdynamic response. The PI Controller IP has an automatic anti-windup function which limits integrator as soon as the PI Controller reaches saturation.In certain applications like motor control, it is important to initialize the PI Controller to a proper value before enabling it. Initializing the PI to a good value avoids jerky operation. The IP block has an enable input to enable or disable the PI Controller. When disabled, the output will be equal to the init input and when enabled, the output is PI computedvalue.PI Controller Parameters and Interface Signals 2. PI Controller Parameters and Interface Signals (Ask a Question)This section discusses the parameters in the PI Controller GUI configurator and I/O signals.2.1 Configuration of GUI Parameters (Ask a Question)The following table lists the description of the configuration parameters used in the hardware implementation of PIController. These are generic parameters that are customizable as per the requirement of the application.Table 2-1. Configuration Parameters2.2 Input and Output Signals (Ask a Question)The following table lists the input and output ports of PI Controller.Table 2-2.

PI Controller Timing Diagramsys_clk_istart_ikp_iki_iref_input_iact_input_iDone_ooutput_y_o4. Testbench (Ask a Question)A unified testbench is used to verify and test PI Controller called as user testbench. Testbench is provided to checkthe functionality of the PI Controller IP.4.1 Simulation (Ask a Question)The following steps describe how to simulate the core using the testbench:1.Open the Libero SoC application, click Catalog tab, expand Solutions-MotorControl, double click PIController, and then click OK.
