本文说明了PID参数自整定的意义，基于继电反馈PID参数整定的原理，并将基于继电反馈PID参数整定方法在MATLAB环境中进行仿真，选择一种生产过程进行应用分析。选择51单片机，设计出计算机控制系统的主要电路结构(This paper describes the self-tuning PID parameters of the significance, based on relay feedback principle of PID parameter tuning, and based on relay feedback tuning method of PID parameters in the MATLAB simulation environment, select the application of a production process. Select 51 microcontroller, a computer control system design the main circuit structure)

针对DVB-T标准ETSI EN 300 744 V1.5.1,设计了可用于DVB-T接收整机的多速率DDC模块,并在FPGA中仿真实现.在复用数字振荡混频模块的基础上,根据输入信号的不同带宽(6M/8MHz)选择不同的抽取滤波器组完成抽取因子为3或4的多速率处理任务,利用两级半带滤波器(HBF)级联完成4倍抽取滤波,单级奈奎斯特滤波器完成3倍抽取滤波. (For the DVB-T standard ETSI EN 300 744 V1.5.1, designed for DVB-T receiver machine multi-rate DDC module, and the simulation in the FPGA implementation. Numerical oscillation in the complex mixer module, based on the input signals of different bandwidths (6M/8MHz) choose a different group of complete decimation filter extracted factor 3 or 4 of the multi-rate processing tasks, using two half-band filter (HBF) cascade to complete four times decimation filter, single-stage Chennai Nyquist filter to complete three times the decimation filtering.)
