Abstract:
1. A control system for a plant, comprising: sliding mode control means for calculating a feedback control input with a sliding mode control so that a controlled output of said plant coincides with a target value; and transfer characteristic adjusting means which is connected to an output of said sliding mode control means, and has a transfer characteristic set according to a transfer function of a controlled object model which is obtained by modeling said plant, wherein a control input to said plant is set to an output of said transfer characteristic adjusting means, and the transfer characteristic of said transfer characteristic adjusting means is set so that a composite transfer function indicative of a transfer characteristic which is obtained by combining the transfer characteristic of said transfer characteristic adjusting means and a transfer characteristic of said controlled object model, coincides with a desired target transfer function, wherein said transfer characteristic adjusting means includes a subtractor and a frequency shaping controller, said subtractor calculates a difference between the feedback control input and the controlled output of said plant, and said frequency shaping controller calculates the control input to said plant by applying a frequency shaping transfer function to the calculated difference.
