AN IMITATIVE RESEARCH ON THE DESIGN METHOD FOR OPTIMUM PID CONTROLLER OF TYPE-ONE DELAYING SYSTEM

介绍了PID调节器参数优化设计原理,通过仿真方法系统地分析了一类滞后系统最优化PID调节器参数设计及其系统稳定的鲁棒性。由于系统参数变化对最优PID调节器参数(K_P、T_I、T_D)及系统动态性能指标的影响,运用连续系统最优PID调节器的参数K_P、T_I、T_D作为离散最优PID调节器的初始值的方法,具有较大的灵活性和适用性。能满足不同系统对不同指标的要求,从而更有效地指导工程设计。

After a detail introduction on the principle of optimum parameter design for PID controller,this thesis provides a systematic analysis for PID controller of type-one delaying system as well as on its robust steadibility, concluding to an engineering-oriented method of robust analysis and design for the systems of this type.Furthermore,this thesis provides a discussion on the influenees of the PID controller parameters (K_P, T_I, T_D)and the influences of the system dynamic properties caused by the changes of system parameters, thus it can be effectively used to guide engineering-oriented designs.
