| Abstract: | This paper analyzes the generating mechanism of surplus torque on electro-hydraulic load simulator in the loading process and its characteristics. On the basis of synchro-compensation for electro-hydraulic load simulator, this paper presents a feedforward compensation method with angular velocity difference of synchro-compensating moter and loading motor to make the second compensation for the surplus torque. The mathematical model of loading system compensated synchronously is exacdy derived, and the synchro-system and the feedforward controller are designed. In comparison with position synchro-compensation, and angular feedforward compensation respectively, theoretical analysis and computer simulation indicate the comprehensive compensation method is quite effective in eliminating surplus torque. |
