Hysteresis Optimization and Experimental Verification of Pneumatic Proportional Valve Driven by Voice Coil Motor
摘要
Abstract
To address the hysteresis and slow response often observed in conventional solenoid-driven pneumatic proportional valves during dynamic pressure regulation,a pilot-operated pneumatic proportional valve driven by a voice coil motor is proposed.A coupled electro-magneto-mechanical-pneumatic dynamic model is established to characterize spool motion,chamber pressure variation,and throttling flow characteristics.Key model parameters are determined through structural dimensions and experimental calibration.The Stribeck friction model is introduced to describe the nonlinear friction of the spool.A co-simulation platform is built in AMESim to reproduce the dynamic hysteresis.To quantify the dynamic process,dead time and response hysteresis time are defined as evaluation indices.Sensitivity analysis is conducted to identify critical structural parameters.A hybrid optimization strategy combining global search via genetic algorithm and constrained fine tuning via non-linear programming by quadratic lagrangian is applied to reduce hysteresis and improve dynamic response while satisfying steady-state error constraints.Simulation and experimental comparisons show that the model accurately reflects system dynamic behavior with small errors.After optimization,the dead time decreases by 30.4%under the 0~0.5 MPa pressurization condition and by 33.3%under the 0.5~0 MPa depressurization condition.The proposed model and structural parameter optimization method effectively enhance the dynamic performance of pneumatic proportional valves.关键词
