The thesis investigates the design and implementation of a fuzzy controller for washing machine drive systems. First, a rotor position estimating technique is proposed for the interior permanent magnet synchronous motor, which is used to drive the washing machine. Next, a fuzzy controller is designed and implemented for the washing machine system to achieve sensorless closed-loop adjustable speed control system. The system has fast transient responses and good tracking ability.
A TMS-320-LF2407 digital signal processor is used as a control central unit to execute the rotor position estimating algorithm and the fuzzy control algorithm. Several experimental results are shown to validate the correctness and feasibility of the proposed system to apply in washing machine. This thesis proposes of IPMSM can give better speed response under the load disturbances or variable speed commands.
