Development of efficient electrobus electromechanical system based on adaptive vector- controlled induction motor drive with accumulator-ultracapacitor power source

An experimental electrical drive for electric buses and traks is developed and experimentally tested. Developed power converter for induction motor based electrical drive provides 100 kW of output power. Flux-torque (speed) control algorithms for induction motor are developed, implemented and experimentally verified. Developed nonlinear controller take into consideration motor's magnetizing curve provides asymptotic flux-torque (speed) tracking, torque per Ampere maximization (MTA) as well adaptation to stator and rotor resistances.

The theory of analysis and synthesis of adaptive electromechanical systems with vector-controlled electrical motors is developed and generalized. Proposed theory allows synthesizing automatic control systems with the properties of robustness to electrical motor parameters variations, thereby improving their dynamic performances and efficiency. Methods for robust adaptive estimation of immeasurable coordinates and identification of unknown parameters of electromechanical converters are developed.
