Multivariable control laws developed by Dr. Brian Porter of the University of Salford, England are used to successfully perform maneuvering tracking tasks with the NASA/Grumman Control Reconfigurable Combat Aircraft (CRCA). Porter's method is used to design discrete Proportional plus Integral (PI) control laws. Output and selected state rate feedback are used. The results in three no failure flight conditions show robust tracking control of the CRCA for five selected maneuvers. Single failures are introduced to test the ability of the fixed-gain designs to successfully control the aircraft and perform the maneuvers. The time responses show that discrete PI control law can make the CRCA successfully perform all five maneuvers for two of the three control surface failures investigated in two of the three point designs. The step response PI control law results in stable control for only one of three failure situations. Keywords: Control theory; Flight control systems; Multivariable control; Adaptive control systems.
