| Summary: | This paper addresses speed control for permanent magnet synchronous machines (PMSMs), specifically focusing on the outer control loop within a cascaded control structure. The proposed approach aims to address the weaknesses of existing methods. One of its key advantages is that it does not require knowledge or estimation of mechanical torque, magnetic flux or inertia. Instead, it relies on a straightforward formula, avoiding the complex algorithms typically used to estimate mechanical characteristics. Additionally, the proposed strategy ensures robust control even in the presence of faults in current sensors. Simulation results demonstrate the superiority of the proposed method compared to recent approaches, and experimental results confirm its viability. |
