Abstract
Model following control is a sophisticated technique of meeting short period handling quality requirements of an aircraft, if all specifications can be embeded into an ideal mathematical model which the aircraft is made to track . Programmes have been developed for computation of model following control laws based on optimal control to minimize model following error and also for perfect model following control .An optimal and a perfect C* model following problem was formulated for satisfying C* criteria 'for an aircraft and the same applied to a design excercise on M-2000 aircraft. It is found to be difficult to meet the short period damping and natural frequency requirements as well as minimize C* error due to limited state feedback available. Hence a technique for pole placement by output feedback has been developed and applied to M-2000 aircraft to get desired short period dynamics and a prefilter designed to keep the C* response within the prescribed envelopes for all three flight conditions considered .
