Optimization of electromagnetic actuator performance for high-speed valves

The dynamic performance of electromagnetic actuators driving on-off control valves is optimized numerically by combining hybrid lumpedparameter/distributed-parameter actuator models with an efficient constrained optimization technique. Two examples of constrained actuator optimization are presented where up to eight design parameters are optimized. One example problem involves minimizing variations in the response time of a fuel injection control valve caused by manufacturing and assembly tolerances, while the other example deals with minimizing the response time of a high-speed gas sampling valve. © 1986 ASME.
