Abstract
WE PROPOSE A NEW COMBINED FEEDFORWARD AND FEEDBACK CONTROL DESIGN METHODOLOGY FOR MULTI-INPUT-MULTI-OUTPUT (MIMO) DYNAMICAL SYSTEMS SUCH AS THE MODERN TACTICAL AIRCRAFT. IN PARTICULAR, THE DESIGN OF CONTROLLERS FOR SUPERAGILITY IS ADDRESSED BY AN INNOVATIVE CONCEPT OF DETERMINING THE UNCONSTRAINED STOCHASTIC OPTIMAL FEEDFORWARD CONTROL LAW TO ACHIEVE HIGH MANEUVERABILITY WITHIN A GREATLY EXPANDED FLIGHT ENVELOPE. THE APPROACH IS APPLICABLE TO HIGH-PERFORMANCE AIRCRAFT WITH STATIC INSTABILITY, NUMEROUS CONTROL EFFECTORS AND THRUST VECTORING WITH REQUIREMENTS FORINTEGRATED AERODYNAMIC, PROPULSIVE AND FLEXIBLE MODES. THE STRUCTURE OF THE OPTIMAL FEEDFORWARD AND FEEDBACK CONTROLLERS AND ALGORITHMS TO COMPUTE THE REQUIRED CONTROL PARAMETERS WILL BE DEMONSTRATED BY SIMULATION OF A TYPICAL DESIGN PROBLEM.
