Abstract :
The synthesis control of force and position in electro-hydraulic servo system has been applied to some special occasions. Analyzed a typical system which adopted this kind of control algorithm. Applying unchanged structure theory, the compensated transfer function has been deduced, the compensated state-space model is presented. Considering the synthesis control should meet the requirement to force and position at the same time , introduced the linear quadratic performance fonctionelle, the optimized control formula of the synthesis control of force and position on total state feedback has been deduced. The simulation results proved that the compensated state-space model has more superior performance.
