According to the requirement of closed-loop frequency spectrum, a new PID parameters solving method based on closed-loop gain shaping is presented. The algorithm shapes the closed-loop gain without selecting weighting functions in H ∞ control algorithm. Its core is to determine the final shape of the transfer function of the closed-loop system, the robust PID controller is directly constructed using parameters having engineering sense. The algorithm guarantees fundamentally that the designed controller has fine control performance and robustness. It has the advantages of simple solving procedure and the obvious physical sense.
