Study on Speed Sensor-less Vector Control of Induction Motors Based on AMEsim-Matlab/Simulink Simulation

摘要

The model of speed sensor-less vector control system of induction motors has been built on the AMEsim and Matlab/Simulink platform, AMEsim and Simulink can be connected by creating an S-function interface. The results of Co-simulation indicate that the algorithms of model reference adaptive system (MRAS) based on counter electromotive force (EMF) can estimate the speed with some accuracy in static and dynamic conditions and make the electro-hydraulic power steering (EHPS) system offer the assist force as quickly as the sensor-based system. So the proposed model and control algorithms are correct and have reached the expectation.
