Research on the cloud computing fuzzy proportion integration differentiation control strategy for permanent-magnet homopolar motor with salient pole solid rotor used on new-energy vehicle

Due to the complex operating conditions of new-energy vehicles, traditional driving motor system has been unable to meet their high-quality requirements for performance. To solve this problem, permanent-magnet homopolar motor with salient pole solid rotor was selected as the research object in this paper, and based on the analysis of its mechanism and mathematical model, a cloud computing fuzzy Proportion Integration Differentiation (PID) control strategy was proposed and applied to the speed control of homopolar motor system. By system modeling on simulation platform, the result showed that cloud computing fuzzy PID control strategy obviously improved the responsiveness, control precision and stability of homopolar motor system comparing with PID control strategy. This verified the validity and applicability of the design and provided a reference and theoretical basis for improving the control quality of driving motor system used by new-energy vehicles (NEV).
