摘要
在分析现有PID控制器参数整定方法局限性的基础上,提出并建立一种多指标约束下PID参数统一优化定量整定方法。给出通过Matlab仿真分析筛选确定PID参数最优组合值的方法,介绍其实用方案:基于原始系统单位阶跃响应曲线估算PID初值的方法、制定多指标约束的方法、筛选PID优化值的具体方案和Matlab仿真软件流程图等,最后给出多个代表性的实例分析。结果表明:该方法能快速完成PID控制系统的优化设计,并且不需要PID参数经验值和计算/调试P控制的临界振荡增益和周期。
Based on analysis of the limitations of now-used PID control tuning methods, a method for consolidated optimizing and quantitative setting under multi-index constraint was proved and established. The method to select and determine the optimum values of PID parameters by Matlab simulation was given, and its practical scheme was introduced： the method for estimating initial values of PID parameters from the unit-step response curve of an initial system, the method for constituting dynamic performance criteria, the scheme for selecting the optimum values of PID parameters, the flow chart of simulating soft, etc. Finally, representative multiple examples are given. The results indicated that this method can quickly accomplish the optimal design for PID control systems, and needn＇t both utilize experiential data about PID parameters and calculate （or tune） the critical oscillation gain and period of a P controller.
