Equal-status approach synchronization controller design method based on quantitative feedback theory for dual hydraulic motors driven flight simulators

A novel equal-status approach synchronization controller design method is presented for improving whole workspace synchronization of flight simulators. The method takes the advantages of transparency for QFT to synthesize equal-status synchronization forward channel controllers, synchronization of which can be evaluated by steady status synchronization conditions. Additionally, feed forward controllers are adopted to fulfill the strict requirement of magnitude-frequency characteristics and phase-frequency characteristics of flight simulators. Three groups of equal-status synchronization controllers are designed according to angle position ranges to satisfy performance specification of whole workspace. Simulation results indicate that controllers designed with the proposed method could achieve performance specification requirements over whole workspace.
