Abstract :
This paper studies the basic structure and principles of the three degrees of the freedom turntable system, and establishes its mathematical model. It describes the design theory and procedures of the variable structure control system, presents a new design method of the variable structure control (VSC) of electrical-hydraulic turntables, analyzes in theory the robustness of the VSC, and discusses the simulation experiments on one type of turntable. Research and experiments have shown that the VSC system is distinguished by its excellent dynamic and steady-state characteristics, and is independent of changes in the plant parameters and external disturbances.
