Summary on Grant Application Form
There is a significant demand for high-performance sensoriess induction machine drives capable of accurately executing torque, speed and/or position reference trajectories. The elimination of mechanical shaft sensors is extremely desirable. This proposal aims to produce a new type of sensoriess high-performance induction motor drive, that solves the sensoriess problems, through collaboration between Heriot-Watt University .(HWU) and the University of Aberdeen (UA). This YAII be achieved by fulfilling three main objectives (responsibilities shown below) which represent novel developments in the area of sensoriess high-performance torque and position/speed control of induction machines:- 1. A new adaptive method for stator current control that requires no knowledge of machine parameters, and is robust to parameter variation. This will help reduce drive commissioning time, compared to vector and direct torque controllers. The latter two techniques are regarded as state-of-the art methods for industrial applications (HWU). 2. A new nonlinear adaptive control method for robust position/speed control of an induction machine that deals specifically with the problem of nonlinear and variable mechanical loads (HWLJ, UA). 3. A new technique for stable speed and position estimation that permits operation in a wide speed range, including zero stator frequency. This enables the sensoriess drive to operate in the entire torque-speed plane (UA).
