   Adaptive Fuzzy Logic Controller for an Induction Motor Supplied by a PWM Voltage Source Inverter
By Pirjan D., Ivanov S.*, Sente P.*, Viorel T.** [View]
[Download]

Abstract: The calculated stator voltage for a flux oriented control (FOC) system of an induction motor fed by a voltage source inverter (VSI), depends by the motor parameters, specially by stator phases resistance, Rs. Also, the power semiconductors are real (there are some voltage drops across the power terminals, for motors until few kW, on the same rage with the product Rsis). Those are a few reasons that require using a bigger value for Rs (to include all those effects) when designing a classic controller. The paper presents a schema that computes the real value for Rs, using for that a Mamdani fuzzy logic controller (FLC). This is performed by maintaining the real (indirect measured) magnetizing current all time equal with its pre-set value.

   Design Method of Fuzzy Controllers for Speed and Current Control Loops of DC Motor Drives
By Stasi S., Salvatore L. [View]
[Download]

Abstract: This paper deals with a simple method to design two fuzzy controllers of a fully digital dc motor drive. The control system has a cascade structure: the outer loop controller realises the usual speed control, while the inner loop one is used to control the armature current. The design method is based on physical relationships of dc machine. The use of fuzzy controllers increases the robustness of the drive to external disturbances, parameter and load variations. The inherent non-linear characteristics of the fuzzy controllers make it possible to obtain fast and accurate tracking of rotor speed references, and to control armature current without exceeding its limit value.

   Extended Kalman Filter Based Speed Sensorless AC Motor Control
By Fodor D., Vass J., Juhász Zs., Bíró K. A. [View]
[Download]

Abstract: The paper describes a method for speed sensorless control of an AC motor. Properly the extended Kalman filter is used for estimating the speed. The EKFT algorithm and its adaptation to the motor model are described by rigorous mathematical representation and they were realised in MATLAB Simulink. The simulation results show good dynamic behaviour suitable for DSP implementation.
