Simultaneous Load Disturbance Estimation and Speed Control for Permanent Magnet Synchronous Motors in Full Speed Range

A new control scheme for improving disturbance rejection in speed control of permanent magnet synchronous motors

The major hurdle encountered in achieving high performance in servo speed control is the occurrence of large relative errors at low speeds due to torque variations. In this paper, it is shown that this problem can be tackled in the case of synchronous motors, by keeping the stator current and the rotor flux nonorthogonal and including an inner position control loop to improve the transient beha...

Passivity-Based Speed Control for Permanent Magnet Motors

This paper addresses the design, simulation and experimental validation of a Permanent-Magnet Synchronous Motor speed control. The control is based on the passivity strategy; special attention is paid on the stability control issue. SIMNON simulations illustrating the torque and speed response of the motor control are carried out to validate the control strategy. The algorithm control was progr...

LPV Control for speed of permanent magnet synchronous motor (PMSM) with PWM Inverter

This paper deals with the modeling, analysis, design and simulation of a robust control method for a permanent magnet synchronous machine (PMSM) supplied with a PWM inverter based on a LPV (Linear Parameter Variation)  standard controller. Under the influence of uncertainties and external disturbances, by a variation of ±150% of motor parameters from the nominal values, the robust performance c...

Speed Synchronous Control of Multiple Permanent Magnet Synchronous Motors Based on an Improved Cross-Coupling Structure

Abstract: Regarding the shortcomings of the cross-coupling control structure during the start-up of a multi-motor with load—namely, a large synchronization error and a long start-up time—this paper proposes a fuzzy self-adjusting cross-coupling control structure. This structure combines a fuzzy self-adjusting filter and an advanced synchronization compensator. The fuzzy self-adjusting filter ad...
