Abstract
To built pilot tracking control strategy model, the combination of sliding model control characteristic and optimal control characteristic is adopted to propose a sliding optimal control method, and the time-varying sliding surfaces are designed so that the system state is on the sliding surface from the beginning of the motion without reaching phase. The system is robust and stable. A parameter selected method of weighting matrix on H∞ control is improved, by which the weighting matrix of linear quadratic optimal control is calculated. To drive the system state variables to the acquisition control switching surface in minimum time, the acquisition control strategy is builed by sliding model control. The main error is regared as a judgement from acquisition control strategy to tracking control strategy. The simulation results show that the pilot variable stategy control is suitable to the real pilot control characteristic.
