• High-speed permanent magnet synchronous generator
• minimum loss
• integrated control
• variable-speed operation

By analysing the loss model of high-speed permanent magnet synchronous generator (PMSG), the analytic formula of loss using quadrature-direct axis current and speed is established. It shows that the total loss is concave function with respect to d-axis current and speed so that the mathematical method of solving the extreme value can be applied and then the explicit expression of the two independent variables direct axis current and the speed at the minimum loss point can be achieved. Considering the effect of the maximum current limitation of the hardware circuit on the system speed operation mode, the minimum loss speed and direct current integrated control strategy are raised. The results show that compared with the traditional algorithm, the algorithm has obvious advantages, and the efficiency of the algorithm is improved by 16.91% compared with the traditional algorithm.
