Abstract

The invention relates to an ultrasonic wave motor transient characteristic testing device and a control system of the device. The device comprises a base and an ultrasonic wave motor arranged on the base, wherein an output shaft on one side of the ultrasonic wave motor is connected with an optical-electricity encoder, an output shaft on the other side of the ultrasonic wave motor is connected with a flywheel inertia load, an output shaft of the flywheel inertia load is connected with a torque sensor through a coupler, the signal output end of the optical-electricity encoder and the signal output end of the torque sensor are respectively connected to the control system, and the control system is composed of an RNNI and an RNNC. The RNNI completes the identification of the input characteristics and the output characteristics of the ultrasonic wave motor under the different control variables and different flywheel inertia loads, and the RNNC achieves the speed / position / torque control output of the ultrasonic wave motor according to the identified result so as to determine the control dynamic characteristic under the different loads and the different control variables. The device and the control system are high in testing accuracy, simple and compact in structure and good in using effect.

Description

technical field [0001] The invention relates to the technical field of motor transient characteristic testing, in particular to an ultrasonic motor transient characteristic testing device and a control system thereof. Background technique [0002] Most of the existing transient performance tests of ultrasonic motors use ultrasonic motors and external hysteresis dynamometers for load adjustment, mainly focusing on the dynamic characteristic test of position / speed, and seldom involve the dynamic characteristic test of torque. Due to the small output power of the ultrasonic motor and the large output power of the hysteresis dynamometer, the hysteresis dynamometer basically operates in its nonlinear part, and the entire test device is huge, so it is difficult to obtain a good transient characteristic test of the motor performance. Contents of the invention [0003] The object of the present invention is to provide a transient characteristic testing device of an ultrasonic mot...
