| Abstract: | This paper builds the mathematic model of electro-hydraulic position and force control system with UO2 Powder as the load.According to the practical working parameters,it simulates the position and force step-responses of the asymmetric cylinder under potion and force control respectively and sets the values of PID controller parameters and proposes a combined position and force control strategy.The simulation result shows that this strategy enables this switching process change to be quick and causes small overshoot. |
