This project aims to investigate and design a sensor-less control technnique for 3-phase brushless DC (BLDC) motors that operate under frequent mechanical impulse loading and near-stall conditions. In contrast to common operating conditions of most BLDC motor drives, these special conditions are unavaoidable in compact robotic applications, where high-energy mobile robots driven by BLDC motors operate in an unpredictable environment with impulse loading from sudden impacts and energy transfer between robots and near stalling consitions. This project aims to develop a sensorless control technique that allows for 3-phase BLDC motor drive to respond quickly under these special impulse loading and stall/near-stall operating conditions.
The project invloves proposing a sensorless control mechanism, and subsequent theoretical analysis, modelling, simulations and bulding a prototype to demonstare the applicablility of the proposed control technique.
