| Abstract: | Under low speed conditions,an instantaneous speed estimation scheme based on state observer was proposed to overcome the weakness of the average speed method based on incremental-type encoder.A simulation model of the control system in Matlab/Simulink was constructed.An simple angular compensation measure was designed to further improve the performance under ultra-low speed conditions.Simulation results validate the method proposed for improving the speed performance under ultra-low speed conditions. |
