抄録

In this paper, a design method of preview control system which does not use LQ approaches is presented.<br>One of the authers has proposed the design methods of IPD and PID type control system based upon partial knowledge about plant dynamics. In these design methods, σi which denotes the first order moment of the impulse response of every control loop in multi-input-output control system is used as a parameter representing the rise time.<br>A preview controller is designed such that it overtakes the delay of response to the reference signal by σi. This preview action has the following effects.<br>(1) For IPD type control system, the tracking and steady-state errors are improved.<br>(2) For I2PD type control system whose design formula is given here, in addition to the effects of (1) the overshoot of response to the step reference signal is suppressed.<br>Two numerical examples are presented to demonstrate the above effects.
