Summary on Grant Application Form |

The 3 year programme aims to research, implement and validate a new approach to sensorless, high performance vector controlled induction motor drives. The target is to achieve the same torque and speed control performance as a conventional vector drive with a speed sensor. Existing sensorless schemes are unable to achieve this. The proposed technique is to employ a rotor slot harmonic tracking algorithm to supply periodic speed updates. These updates then tune a speed estimator against variations in the motor parameters. The speed estimator feeds the vector controller. Research into both batch and recursive speed tracking algorithms will be carried out. The system will be implemented experimentally on a vector drive rig using a network of Transputer parallel processors and fast signal processors. Variation conventional sensored and sensorless vector drive strategies. If the research is successful the probability of commercial application is very high. A research worker for 3 years and equipment for the experimental rig is requested.
