文摘
- •
First in-depth control performance data from a novel piezoelectric hydraulic valve.
- •
Proof of a generalised Prandtl-Ishlinskii model fitting piezo-device hysteresis.
- •
Experimental demonstration that the inverse model effectively reduces hysteresis.
- •
Detailed comparison of closed loop control with and without hysteresis compensation.
- •
Valve performance comparable to commercial valves with more complex costly actuation.
