A hybrid adaptive control for flight simulator turn table

This paper deals with the conventional model reference adaptive control (MRAC) and replaces conventional control technique such as PI control with a novel hybrid adaptive control law based on the proportion and differential gains. The advantages of the hybrid adaptive control against the pure continuous-time adaptive control are also discussed. From a practical standpoint, the infrequent adjustment of the control parameters makes for more robust adaptive control while from a theoretical point of view, the algorithms are attractive since they provide a unified framework for the design of hybrid adaptive control system. The stability of the hybrid adaptive control law also can be assured by using the Lyapunov stability criterion. Simulation results verified the availability and effectivity of the proposed method. Especially, it is of great importance for the systems to improve the tracking accuracy and resist external disturbance.
