Abstract

The purpose of the paper is to propose a new high-performance optimal position servo of an induction motor fully controlled by a micro-computer, which was designed and realized through a waterfall type top-down design in a newly developed CAD environment. Field-orientation control was used to design a new voltage-controlled optimal regulator for position control. Globally stable observers were designed and utilized to overcome the restricted availability of sensed variables: winding voltages & currents and shaft speed & angle. The digital scheme was experimentally tested and verified. Also shown is the effect of quantization errors and sampling period in A/D's & D/A's on the response and accuracy of the control system.
