This paper proposes a compensation algorithm for reducing the position errors that are due to two nonideal output signals of a resolver in the vector control of a permanent magnet synchronous motor. Practically, a resolver generates periodic position errors because of the amplitude imbalance and imperfect quadrature between the two output signals of the resolver. As a result, the dq-axis currents...
The permanent magnet synchronous motor (PMSM) is very useful in applications. Vector control of PMSM is popular kind of its control. In this paper, at first an optimal vector control for PMSM is designed and then the results are compared with conventional vector control. Then, we assumed that the measurements are noisy and linear quadratic Gaussian (LQG) methodology is used to filter the noise. The...
