Abstract

A hybrid control strategy has been designed and developed for the electro-hydraulic position servo control system with generalized pulse code modulation (GPCM), which is suitable for the occasion that the work condition is poor and a large flow rate is required. The control strategy integrates the merits of bang-bang control, PID control and fuzzy control. With this hybrid control strategy, the electro hydraulic control system has good performance, and the servo control is carried out with GPCM through on-off valves.
