High-Order Filtered PID Controller Tuning Based on Magnitude Optimum

The paper presents a tuning method for PID controllers with higher-order derivatives and controller filters (HO-PID), where the filter orders can be arbitrarily chosen by user. parameters are tuned according to magnitude optimum criteria specified noise gain of controller. advantages proposed approach twofold. First, all obtained from process transfer function or measured input output time responses as steady-state changes. Second, priori defined limits amount HO-PID noise. Therefore, successfully applied in practice. work shows that significantly improve control performance various models compared standard controllers. Of course, increased efficiency is limited selected gain. illustrated on several two other methods
