Parameters of the secondary unit system, similar to other electrohydraulic servo systems, change with the operating condition and time. It is certain that the system performance will be affected. The application of the robust optimal controller in the speed control of a secondary unit system is examined in this paper. This controller consists of an optimal part and an auxiliary part. The optimal part is utilized for specifying the dynamic characteristic of the whole closed-loop system, which is designed based upon the ARMA (autoregressive moving-average) model. The auxiliary part is developed for rectifying the uncertainties which a simple ARMA model is unable to handle. The robust optimal controller is demonstrated from the results of a series of simulations and experiments to be superior to the suboptimal PI controller under the situation of a change in working pressure and load inertia. The proposed control scheme is also indicated by these results to be robust to the external torque disturbance.
