Design Method Of Multi-input Multi-output Delay Time Control System With Feedforward Compensation

摘要

For the design of MIMO delay time control systems the concept of the minimum-phase state of the controlled object of Fig. 1 is proved to be important. By the feedback on the observed minimum-phase state, the control system can be stabilized diminishing the effect of delay times. And feed forward compensation is expected on a standpoint to cancel delay times in the input-output characteristics.rnFor the delay time control systems the decoupling control is necessary. And the design of decoupling tandem compensator with the minimum degree is shown as Fig. 2. The feedback on the observed minimum-phase state and the feed forward compensation are also useful for delay time decoupling control systems.
