摘要：This paper presents analysis and design of a family of controllers based on
numerical convex optimization for an aircraft pitch control system. A design
method is proposed here to solve control system design problems in which a set
of multiple closed loop performance specifications are simultaneously satisfied.
The transfer matrix of the system is determined through the convex combination
of the transfer matrices of the plant and the controllers. The present system
with optimal convex controller has been tested for stability using Kharitonov’s
Stability Criteria. The simulation deals here with the problem of pitch control
system of a BRAVO fighter aircraft which results in higher order close loop
transfer function. So the order of the higher order transfer function is reduced
to minimize the complexity of the system.
