Many modern high performance aircraft employ high gain manoeuvre demand systems to improve their stability and pilot handling qualities. The frequency response of the primary actuation systems used in such aircraft is of crucial importance. Phase lags at low frequency can inluence the pilot handling qualities and high bandwidth is required to minimise the impact of the actuator on the gain and phase margin of the flight control system. The control of advanced primary flight control actuation systems is discussed. Two alternatives to conventional loop closure have been evaluated on a full actuation system hydraulic test bench incorporating a representation of the control surface resonance effects. Results show that increases in bandwidth and reductions in low frequency phase lags have been achieved. Recommendations for further work to obtain additional frequency response improvements and evaluate the impedance effects are made.
