Variable Load Electric Vehicle Speed Regulation Feedforward Compensation Composite Controller

A feedforward compensation composite control method for a variable load electric vehicle speed regulation system transforms the traditional control model based on surface-mounted permanent magnet synchronous motors into a state equation of system error. This method effectively characterizes the system’s adaptability to variable load conditions. By combining the boundary term with the first and second system states, a feedforward compensation composite control is designed and its stability is proven. Both theoretical and practical validations demonstrate the effectiveness of the designed method.
