To address the problems of high operating power and easy wear of the mechanical structure of the electric drive mechanism bearing heavy load,this paper introduces a combined air-float electric drive scheme.Firstly,the working principle of the air-float-electric cylinder and electric and air driving force and power matching are analyzed,and then the pneumatic system model predictive control(MPC)algorithm is designed to reduce the electric system power by taking the electric system power as a prediction variable.The simulation result shows that the pneumatic system after applying MPC algorithm shares a larger driving force and reduces the electric system power significantly.
