Tuning of PID Controller for the Integrating Systems

According to the idea of the system identification, 2-DOF PID based on the desired dynamic equation (DDE-PID) has been improved. The DDE-based PID is applied to the integrating system. This method only needs the step response information of the plant, which is easy to be obtained. According to the physical meaning of parameters, the tuning is also convenient to meet the requirement of the dynamic performance. The simulations show that the method has the low overshoot and the short setting time on the integrating system.
