In this work is presented predictive speed controller for induction motor. It is proposed to divide the control process into two parts: coarse adjustment and regulation in the area of steady state. This allows to reduce the pulsations in obtained waveforms in steady state.
The paper presents a complete solution for speed sensorless control system for five-phase induction motor with voltage inverter, LC filter and nonlinear control of combined fundamental and third harmonic flux distribution. The control principle, also known as multiscalar control, nonlinear control or natural variables control, is based on a use of properly selected scalar variables in control feedback...
This paper analyzes the dynamic performance of FOC induction machines operating under current and voltage constraints. FOC rely on the proper performance of the inner current control loops. The capability of the machine to increase its torque can be seriously compromised due to the inverter voltage and current limits, which affect to the current regulator transient response. This can be especially...
