Abstract

The invention relates to a hardware-in-the-loop simulator and a hardware-in-the-loop simulating method. The hardware-in-the-loop simulator is connected with a driving device and is used for hardware-in-the-loop simulating a motor, a mechanical device and a transmission system connected with the motor. The hardware-in-the-loop simulating method comprises steps of obtaining motion signal and corresponding data measured by a sensor according to driving signal of the driving device, the model of the motor and the model of motion shaft of the motor through a motion simulating unit; and simulating output signal of the sensor through an output unit according to the data measured by the sensor, and feeding back the simulated output signal to the driving device. The hardware-in-the-loop simulator and implement way of the method can be adapted to signal simulation of different type of sensors and can conveniently simulate a motion control system using digital sensor, such as an encoder or an interferometer and the like as a feedback device.

Description

technical field [0001] The invention relates to simulation technology, in particular to a motion control hardware-in-the-loop simulation device and method. Background technique [0002] Simulation is a technology that uses a model to reproduce the working process of an actual system and studies the actual system through experiments on the system model. When the actual system being studied is expensive, or the experiment is dangerous, or it takes a long time to understand the consequences of system parameter changes, simulation is an effective research method. [0003] Simulation technology is widely used in various fields and products. Taking electromechanical products as an example: there are various mechanical transmission devices in electromechanical products. The received electrical signal is converted into angular displacement or angular velocity on the motor shaft, and these motion signals are output. In order to improve the accuracy and precision of mechanical parts...
