Ac motor control using predictive control scheme
(UNIVERSITY OF MANAGEMENT AND TECHNOLOGY, 2015) Mehmand, Muhammad Shahrukh Khan; Murad, Javeria; Ehsan, Asima
Ac motor is widely used in industry for a long time.It is used for various purposes. Because of its larger use in industryits control strategies have given much importance in last decades. There are many issues related with it but the commonly faced issue is its speed control. Speed of motor varies as the load changes and abrupt the system. A regular change in voltage and frequency is required to keep the speed of motor constant. Different Control Schemes are available for speed controlling of motor. Predictive control scheme is latest technique used for speed control. MPC has become popular because of development in digital control platform. It is a multi-input multi-output scheme. It predicts the future behavior of system and generates the control signals accordingly. It has modulation based implementation. SPWM is the simplest modulation technique used for the controlling of converter. Controller passes control signals to Converter which generate the required Voltage signals.
