Torque control using metaheuristic optimization for optimal energy consumption of a BLDCM

The emergence of electrical energy in the field of vehicle traction remains a major preoccupation of electro technicians today after a long absence, owing to the collective commitments and responsibilities of the states and automobile manufacturers as well as the advances made in various technological and scientific fields and more precisely the optimization of the electrical energy consumed by the motor. In this paper, we present a method of control of a Brushless Direct Current Motor (BLDCM) during the traction of an autonomous robot. This is done by optimizing the power consumed by the motor to find the optimal current and then find the optimal torque to function the machine. Then we optimize the energy of the traction to find the optimal slip ratio and the optimal linear velocity for an optimal operation that allows us to reuse the lost energy.
