| Abstract: | The problem of sl ow steprespon se in electrostrictive actuator is studi ed and a digital PID method is proposed to compensate the slow step response．A m icrocomputer control system has been designd and made．We also design a precise h igh-voltage adjustor，and it cooperates w ellwith digital hardware system and for ms a integrated and practical control sy stem toimprove the characteristics of t he electrostrictive actuator．The experim ents show thatthe control system is a s imple，reliable，and practical one，and the result ofexperiments is very ideal． |
