Abstract :
The state-space equation of the hydrostatic transmission system with secondary regulation is derived and the exact linearization method of nonlinear system is proposed to transform the nonlinear system into a linear controllable one by coordinates transformation and state-space feedback. Based on the linearization model, the control law is achieved through optimal control theory of linear quadratic regulator. At the same time, the influences on system performance of weight matrix are discussed. Finally, the simulation results show that the system with designed controller is not only free from the system steady error and overshoot, but also has good robust ability
