Abstract :
An inexpensive servo-motor-driven hinge-arm actuator device has been realized with the capability of producing linear displacements on the order of 0.5 ¿in. The device is applicable to precision control of machine tools and alignment of optical systems. Transfer-function and calibration data for the actuator are given. A closed-loop alignment control system incorporating the actuator and linear differential transformer (LVDT) sensors has a precision of 0.05¿ with a dynamic range of ±3.5¿ and a response time of 2 s.
