Optimized Parking Control for Electric Vehicle Driven by Switched Reluctance Motor
IEEE ACCESS(2023)
Abstract
Sufficient and stable positioning torque is necessary for the parking of an electric vehicle driven by switched reluctance motor (SRM). Considering the highly nonlinear torque characteristic of SRM, the parking control with high stability and power consumption economy is an important issue. This paper presents an optimized parking control method for an electric vehicle driven by SRM to achieve optimal parking stability and power consumption economy simultaneously. The static torque-angle characteristic curve of a four-phase 16/12 SRM is analyzed, based on which the optimized region of parking position (presented by rotor angle) is obtained considering the uncertainty of parking conditions. To ensure the vehicle is properly parked in the optimized position region, active disturbance rejection control (ADRC) is utilized to achieve the smooth switch from zero-speed control to parking position control. Simulation and experimental results verify that the proposed method can better stabilize the parking on the ramp and reduce power consumption in all conditions.
