ABSTRACT:
A control system for a plant, including a sliding mode controller and a transfer characteristic adjusting module. The sliding mode controller calculates a feedback control input with a sliding mode control so that an controlled output of the plant coincides with a target value. The transfer characteristic adjusting module is connected to an output of the sliding mode controller, and has a transfer characteristic set according to a transfer function of a controlled object model which is obtained by modeling the plant. A control input to the plant is set to an output of the transfer characteristic adjusting module. The transfer characteristic of the transfer characteristic adjusting module is set so that a composite transfer function indicative of a transfer characteristic which is obtained by combining the transfer characteristic of the transfer characteristic adjusting module and a transfer characteristic of the controlled object model, coincides with a desired target transfer function.
