Flux and Speed Observer for AC Motor Sensorless Control
Original language description
Control of drives based on AC induction electrical motors is a quite complex task. If vector control algorithms are used we need to know not only rotation speed of the motor but also the position of the magnetic flux inside the motor during the control process. There is of course possibility of using flux and speed sensors and the control based on measured values. Flux sensors are quite complicated and expensive, that is why it is good idea to use computed values of the flux instead of measured values.But there are also applications in which even speed sensors should be omitted to achieve the cost reduction and a simpler mechanical construction. In such situation we have to solve task of the state reconstruction only from voltages and currents measurements. In the paper we present simple method based on deterministic evaluation of measurement. The method uses AC induction motor model and simple adaptation equations to estimate rotor magnetic flux and speed from measured electrical qua
