- Abstract:
-
In order to make the design of the low gravity simulating system simpler and make the lunar rover get more accurate test results, the method of controlling the force circuit and the location circuit directly is put forward. In the system model, the delay problem and the parameter uncertainty which may affect the robust stability of the system are considered. For addressing the problem of the interference and the uncertainty in the system, H∞ controller is designed. Experiments showed that the controller can effectively suppress the influence of uncertainty and interference and the control precision of the system is guaranteed.
