Design Method Of Multi-input Multi-output Minimum-phase State Control System With Decoupling And Feedforward Compensation

摘要

Decoupling control of multi-input multi-output (MIMO) linear system still remains to be important control problems. In the state space method the feedback decoupling control introduced in the past seems to be much complicated for the design and adjustment in the actual applications.rnIn the transfer function method, the tandem compensator matrix preposition-ed at the input side is fundamental. However the proper and stable compensator is sometimes difficult to be designed.rnGenerally the decoupled MIMO object often has the property of non minimum-phase, and the compensation for the minimum-phase is necessary.rnIn this paper a new configuration of the tandem decoupling compensator with the minimum degree is shown for the square (the same number of inputs and outputs) object transfer function matrix. And the feedforward compensation makes the non minimum-phase effect of the decoupled scalar system change to the delay times.
