Adaptive compound control for test turntable

In this paper, A model reference adaptive compound control algorithm is proposed for the test turntable system with unknown or slowly time-variant parameters. The combination of the general classical feedback correction and the adaptive feedforward compensation can ensure that the test turntable system always gets good performance of the output tracking the input and retains the capability of disturbances suppression. The model reference adaptive compound control law based on the Popov stability theory is designed rigorously in a systematic fashion. Numerical simulation results verify the adaptive compound control algorithm is designed to guarantee the system stability and the servo performance as well as the expansion of system bandwidth, and the tracking accuracy of test turntable system is improved.
