Hybrid Force/Position Control Investigation of Parallel Machine Tool with Redundant Actuation

Abstract:

Article Preview

A novel redundantly actuated parallel machine tool was introduced. The inverse kinematic of 5-UPS/PRPU PMT with redundant actuation was analysed and the driven force of redundant actuation limb was planned. The force/position hybrid control strategy and dynamic differential calculation control strategy were proposed. Then the experiment of evaluating dynamics in the position control mode and in the force/position hybrid control was carried out respectively. The experiment shows that, the force/position hybrid control can improve driven torque of each limb better, balance the load of each limb and is of great help for enhance the dynamic performance of entire PMT.
