Energy Consumption Optimal Control Method of Electric Active Stabilizer Bar

In order to solve the problem of high energy consumption of the electric active stabilizer bar caused by the large torque ripple of the permanent magnet brushless DC motor, a new control algorithm was proposed for three-closed loops. In the outer loop, the PI controller was arranged for motor running angle control. In the middle loop, the PI controller was for the rotate speed control. The optimal control algorithm was used in the inner loop for the stator current control. Based on Simulink softer, 14 DOF vehicle model, electric active stabilizer bar system and its controller model were established and simulated. The simulation results show that the new algorithm can effectively improve the roll stability and ride comfort of vehicle and output performance of motor. The energy consumption of the system is also reduced.
