Speed-Control Strategy of Energy Regulation Based Variable-Speed Electrohydraulic Drive

Article Preview

Abstract:

Dedicated to the disadvantage of variable-speed drive, the energy regulation based variable-speed electrohydraulic drive is proposed. It is a novel solution by adding an energy regulation device and a flow valve into the system. It combines the advantages of variable-speed drive, valve control and energy regulation. But it is a multiple-input multiple-output control system, coupled with strong nonlinear, volatility and uncertainty of some parameters, which make the control strategy complicated. The multiple-compound PID control strategy, as well as the parameter tuning rule, is proposed.
