【Abstract】 Dynamic model is presented for the servo loading system with secondary regulation. The dynamic performance of the system under the effect of parameter changes and coupling disturbances was simulated with MATLAB. Simulation results reveal that the equivalent rotational inertia and the equivalent damping factor of the loaded object mainly affect the transient performance of the system. While the load pressure fluctuation, the load torque fluctuation and the rotational speed fluctuation mainly affect the steady performance of the system.更多还原
