APPLICATION OF COEFFICIENT DIAGRAM METHOD TO DUAL-CONTROL-SURFACE MISSILE

摘要

The normal acceleration control of dual-control-surface missile is a typical MIMO problem, where various modern control design techniques are employed. Coefficient Diagram Method (CDM), with proven effectiveness in SISO or SIMO control design, has been applied to this MIMO problem. It is shown that MIMO design problem can be decomposed into series of SIMO problems, and feedback controller can be designed step by step with CDM. The extra freedom in design is used to design feed-forward controller of various characteristics. The meaning of extra freedom typical in MIMO system is clarified.
