A kind of transfigured loop shaping controller is presented. The transfigured loop shaping system puts the controller K on the feedback loop, while putting the DC gain of the controller K on the reference signal line. It is shown by frequency domain analysis and simulations that the transfigured controller can improve the dynamic behavior of the system. This method of the transfigured loop shaping controller is simple and effective corresponding to the mixed sensitivity method of robust control theory, which improves the behavior of the system by iterative tuning of weighting functions. Satisfactory control results are obtained when it is applied to the design of an autopilot for ships.
