摘　　要：提出一种基于Lambda整定方法的积分对象PID参数整定方法,给出期望闭环时间常数λ的选择原则。针对纯比例控制存在系统余差的问题,引入比例积分控制。仿真试验表明,采用笔者所提方法可一次得到合适的PID初始参数,提高了基于Lambda整定方法的积分对象PID参数整定的鲁棒性和适用范围。A Lambda tuning method for the PID parameter tuning of integrating process was proposed and the selection principle of expected closed loop time constantλwas given.Considering the system residual in pure proportional control,the proportional integral control was introduced.Simulation tests show that,the proposed method can be used to obtain the appropriate PID parameter at one time and it can improve both robustness and application range of the PID parameter tuning of integrating process based on Lambda tuning method.
