Then applying Human Simulated Intelligent Control algorithm to the turntable control system has been designed to resolve the problems, which the load of the pitch channel is asymmetric and the rail's friction is uneven. The method has been verified in the real control system, and meets the requirements of the precision of turntable position. In finally, the algorithm has been simulated and tested correctly in matlab.
