Predictive Feedforward Control Based on Speed Error for Speed Ripple Suppression in Compressor Motors

Iterative Tuning Feedforward Speed Estimator for Sensorless Induction Motors

For speed sensorless induction motors under field-oriented control (FOC), where the motor speed and angle are not measured, the speed control tracking bandwidth is mainly limited by the convergence rate of the state estimator. Prevailing speed-sensorless induction motors suffer significant performance degradation from removing the encoder, which limits their applications to fields requiring low...

An indirect adaptive neuro-fuzzy speed control of induction motors

This paper presents an indirect adaptive system based on neuro-fuzzy approximators for the speed control of induction motors. The uncertainty including parametric variations, the external load disturbance and unmodeled dynamics is estimated and compensated by designing neuro-fuzzy systems. The contribution of this paper is presenting a stability analysis for neuro-fuzzy speed control of inducti...

On speed control of induction motors

In a recent paper 3] Espinosa and Ortega presented an output feedback globally stable speed tracking controller for induction motors. An important feature of the scheme is that it does not require state observers, thus reducing the computational burden, a critical limiting factor in physical implementations. The performance of the scheme is limited by the fact that the convergence rate of the s...

Speed Control Methods for Stepper Motors

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...
