Abstract:
Miniature actuators are the critical components in
the robotic applications with high intelligence, high mobility and
small scales. Among various types of actuators, linear actuators
show advantages in many aspects. A miniature short stroke PM
tubular linear actuator for the micro robotic applications is
presented in this paper. The actuator is deliberately designed
based on the optimal force capability and a proper sensorless
control scheme is developed for the driving of the actuator.
Experiment both on the prototype of the actuator and the drive
system show the validity of the design.
