摘要：
To meet the rising performances requirements of flight simulator, a novel robust perfect tracking control (PTC) strategy was proposed. On account of the PTC's dependence on accuracy of the mathematical models of the controlled plant, the disturbance observer (DOB) was introduced to eliminate the model perturbation and the external disturbance so that the input-output characteristics of the plant is always close to the nominal model within the given frequency band. The simulation results show that the proposed strategy is of good tracking performance even though integrated with the simple PID closed-loop controller. The concrete design method of PTC and DOB were provided in detail. The simulations compared with the existing method were conducted. The results indicate that the proposed method has better tracking performance and stronger capability on disturbance attenuation. ©, 2014, Editorial Department of Electric Machines and Control.
