| 英文摘要 | To check driving performance of the sun directional device, a semi-physical test system is set up on the ground based on electric load simulator. The problems, such as the big torque, high precision and high frequency noise which the control of the test system is confronted, caused by the characteristics of the flexibility and the large inertia of the solar arrays has been solved. In this paper, the mechanism model of electric load simulator is established, and the parameters of the loading unit are identified by the least square method, then the significance of each parameter to the response characteristic of loading unit is analyzed. Then, the controller of the loading unit is designed based on the compound control algorithm, including differential negative feedback, lead compensation and fuzzy adaptive PID, which effectively broadens the bandwidth of the loading unit and improves the dynamic performance. At last, step signal, sinusoidal signal and other signals are used to check the response speed, loading bandwidth and loading accuracy of the test system. The feasibility and effect of the compound control algorithm method are also proved by experiments. |
