In this thesis , conducted in the context of a grant CIFRE between laboratory ECS-Lab and the company GS Maintenance, we focused on the control and observation of electrical systems, particularly multicellular converter series and the series DC motor.The floating voltages of the multicell topology need to be balanced to specific values. PWM control techniques provide such a balance but favor the slow dynamics. Moreover, if the numbers of cells is not prime, there exist duty-cycles which could destabilize the converter. To overcome these drawbacks, we propose direct control strategies based on sliding mode techniques for 2 and 3-cell converters. These are simple, allow fast dynamics, and can be easily extended to any number of cell with lit...
