Approximate Predictive Control of Ac Electric Drives

This thesis deals with the development of model predictive control of ac electric drives with long prediction horizons and yet with computational cost of the algorithm comparable to conventional cascade control approaches. The basic idea is to approximate the cost to go function of dynamic programming taking into account long prediction horizon. For specific cases (linear model and quadratic co...

Sensorless Motor Drives with Predictive Current Control

Hardware complexity of a motor drive can be reduced by estimating controls rather than measuring using sensors. In this way the corresponding sensors are eliminated and the system becomes more robust. This article is about speed control of a sensor less induction motor with predictive current controller technique. This particular speed control technique does not require direct measurements of m...

Torque Control of Brushless Direct Current Motor Drives Using Single Current Sensor with High Reliability

Due to the simple structure, high torque density, low maintenance, and high efficiency, brushless direct current (BLDC) motors are widely used in automation and industrial applications. A control strategy based on single current sensor is proposed for a four-switch three-phase BLDC motor system to lower cost and improve reliability. The whole working process of the BLDC motor is divided into si...
