Flight Control Law Design Method Based on Linear Matrix Inequality Theory

摘要

High performance and low cost are the mostimportant factors in developing flight control systems.Linear Matrix Inequality (LMI) theory is used to designflight control laws that satisfy various controlrequirements, and scheduled control laws with highdegree dynamics that ensure high control performanceunder a variety of flight conditions. This reportdescribes new LMI-based flight control law design anda trial design result for a longitudinal flight controllaw for Automatic Landing Flight Experiment (ALFLEX)for future Japanese space shuttle vehicles. Thestability margin of the control system is directlydesigned and repetition of the design process is reduced.
