  1. In the third chapter, the mathematical models of project system have been established, and simulation has been done on the simulink enviroment of matlab software kits. the simulation focus on the effects of main parameters on the dynamic characteristics of speed control system, and the main parameters include viscosity damp coefficient and friction torque of electrical motor shaft, internal leakage coefficient of pump / motor of hydraulic circuits, gas volume of pressure accumulator, viscosity damp coefficient of cylinder piston and different running building floors, etc. at last, theoretical research effects of the flow and pressure pulsation of pump / motor on car speed and oil volume leakage theory are discussed. the fourth chapter of this thesis concerns the research on the key items about hydraulic power control system according to the ens 1 - 2 and other hydraulic elevator standards
