Direct current (DC) series motors have the highest starting torque of similar kilowatt motors. For a DC drive electric car with a series motor, the conventional close loop speed based control causes not only jerk but tire slip during startup. To overcome this problem, in this paper direct current control is applied to a four quadrants DC chopper (FQDC) to solve the startup problem. A sliding mode controller is used as close loop feedback to control the fluctuated series motor rising current during start up. The controller offers robust and disturbance rejection advantages. MATLAB/Simulink simulation software is used to simulate and test the FQDC during startup which is running in driving mode chopper operation. The controlled sliding mode result shows good performance beyond acceptable.

摘要

Direct current (DC) series motors have the highest starting torque of similar kilowatt motors. For a DC drive electric car with a series motor, the conventional close loop speed based control causes not only jerk but tire slip during startup. To overcome this problem, in this paper direct current control is applied to a four quadrants DC chopper (FQDC) to solve the startup problem. A sliding mode controller is used as close loop feedback to control the fluctuated series motor rising current during start up. The controller offers robust and disturbance rejection advantages. MATLAB/Simulink simulation software is used to simulate and test the FQDC during startup which is running in driving mode chopper operation. The controlled sliding mode result shows good performance beyond acceptable.
