基于Lambda方法的自衡对象PID整定研究

Research on Lambda Based PID Tuning Method for Self-regulating

针对过阻尼和欠阻尼自衡对象,传统的PID参数整定方法因鲁棒性不足而不适用,提出了基于Lambda方法的PID参数整定方法。该方法利用自衡对象的阶跃响应曲线,通过作图的方法给出了PID参数整定的基础参数,并按公式计算得到被控对象的PID参数。通过仿真实验证明:该方法适用范围广,得到的PID控制参数鲁棒性强,是比较先进的PID整定方法。

Concerning over damping and under damping self-regulating object,conventional PID parameter tuning method is not suitable due to the insufficient robustness.Lambda method based PID parameter tuning method is proposed.With adopting the step response curve of self-regulating object,the basic parameters of PID parameter tuning are given by drawing method,and the PID parameters of controlled object is calculated and obtained according to the formula.The simulation experiment indicates the method has a wide range of application.The obtained robustness for PID control parameters is strong.The method is a more advanced PID tuning method.
