【Abstract】 The development of a high-precision position system design method for robotic multi-DOF manipulator using traveling-wave ultrasonic motor and step motor is put forward. High-precision positioning control method of manipulator based on micro-step control method using TRUSM is introduced. A novel precise position control method of TRUSM which has features of practicability is introduced and theoretical and experimental studies are completed. Moreover, the paper dedicated to study on the position error analysis and control system design method. The methods and conclusions put forward in the paper can highly enhance precision of position of USM and have broad prospect in application. The control system for the manipulator with multi-DOF realizes the high-precision control to the joint without using high precise angular sensor.更多还原
