摘　　要：PID的控制性能取决于其参数整定。PID的整定方法众多,不同被控对象采用不同的整定方法,其控制效果有较大的差距。目前,研究缺乏对PID参数整定方法选择的指导,为此,通过5种范例,从时域及频域分析对比PID整定方法的特性,为PID参数整定方法的选择提供参考。结果表明,若想获得快速的响应,可选择Ziegler-Nichols(ZN)调参法;若想获得温和的响应曲线,可选择NCC调参法。The control performance of PID depends on its parameter tuning.There are many tuning methods for PID,and different tuning methods are used for different controlled objects,resulting in significant differences in control effectiveness.At present,there is a lack of guidance on the selection of PID parameter tuning methods in research.Therefore,through five examples,the characteristics of PID tuning methods are analyzed and compared from the time domain and frequency domain,providing reference for the selection of PID parameter tuning methods.The results show that if you want to obtain a fast response,can choose the Ziegler Nichols(ZN)tuning method,and if you want to obtain a mild response curve,can choose the NCC tuning method.
