【Abstract】 The hydraulic-servo system of the precise straightening machine is the executive body and is the essential condition to realize straightening technics. According to the theory of modern control, based on analyzing working character of precise straightening machine, the state space model of the hydraulic-servo system was established and the optimal control of gradual approach track system was designed. The results of simulation showed that the track system had better dynamic character and track capability.更多还原
