Abstract

The components and work principle of Separate Meter In and Separate Meter Out(SMISMO) load sensing control system are introduced. In the novel system, the traditional proportional valve is replaced by the separate meter in and separate meter out valve element which is used to control velocity of piston in the asymmetric cylinder. Nonlinear simulation model of the novel system is built to study the trajectory tracking performance, Linearization Feedback technology is used to linearization the nonlinear system, Calculation Force Control strategies is used for trajectory tracking, simulation and experiment show the tracking performance is good, and the controller is better than pid control strategy, it is promising for industrial application.
