比例-积分-微分(PID)是过程控制中最常用的一种控制算法。算法简单而且容易理解,应用十分广泛。但由于应用领域的不同,功能上差别很大,系统的控制要求及关心的控制对象也不相同。数字PID控制比连续PID控制更为优越,因为计算机程序的灵活性,很容易克服连续PID控制中存在的问题,经修正而得到更完善的数字PID算法。本文以三相全控整流桥阻性负载为实际电路,控制主电路电压,旨在提出一种智能数字PID控制系统的设计思路,并给出了详细的硬件设计及初步软件设计思路。 PID控制系统采用高性能、低功耗的ARM微处理器S3C44BO作为核心处理单元,内部的10位ADC作为信号采集模块,采用了矩阵键盘和640*480的液晶作为人机接口;串口作为通信模块实现了上位机的监控。采用芯片内部自带的PWM模块,输出16M Hz PWM信号并经过一阶低通滤波器得到0~5V的控制信号用于触发主电路控制器,实现PID整定。 软件方面,分析和研究了uC/OSⅡ的内核源码,实现了其在32位微处理器上的移植,作为管理各个子程序执行的系统软件。选用了图形处理软件uC/GUI用于完成LCD显示及控制。PID算法采用了增量式数字PID算法,采用规一化算法进行参数选取。上位机部分采用了C#语言进行编写。另外,采用了RTC(Real Time Clock)作为系统时钟,可以实现系统的定时运行、定时模式切换等。在上位机上也可以方便的控制程序的执行,实现远程监控。 在论文的最后详细的介绍了智能PID控制系统在三相全控桥主电路中的具体应用。总结了调试中遇到的问题,对今后工作中需要进一步改善和探索的地方进行了展望。

NXP Semiconductor designed the LPC2400 microcontrollers around a 16-bit/32-bitARM7TDMI-S CPU core with real-time debug interfaces that include both JTAG andembedded Trace. The LPC2400 microcontrollers have 512 kB of on-chip high-speedFlash memory. This Flash memory includes a special 128-bit wide memory interface andaccelerator architecture that enables the CPU to execute sequential instructions fromFlash memory at the maximum 72 MHz system clock rate. This feature is available onlyon the LPC2000 ARM Microcontroller family of products. The LPC2400 can execute both32-bit ARM and 16-bit Thumb instructions. Support for the two Instruction Sets meansEngineers can choose to optimize their application for either performance or code size atthe sub-routine level. When the core executes instructions in Thumb state it can reducecode size by more than 30 % with only a small loss in performance while executinginstructions in ARM state maximizes core performance.

Abstract: This application note explains how to design an intelligent lighting controller that senses and measures the ambient lightlevel with an ambient light sensor (ALS). Equipped with a real-time clock (RTC), the controller also knows when to turn lighting on oroff at specified times. The system presented in this document can be used to control all luminaires that are mains-supply operated.Controller software is also provided in hex format.

This book is intended for embedded system programmers, consultants and students interested in real-time operating systems. μC/OS-II is a high performance, deterministic real-time kernel and can be embedded in commercial products (see Appendix F, Licensing). Instead of writing your own kernel, you should consider μC/OS-II. You will find, as I did, that writing a kernel is not as easy as it first looks.
