Fuzzy adaptive control of a multimachine system with single inverter supply
Fuzzy controllers are a powerful tool for controlling complex processes. However, its robustness capacity remains moderately limited because it loses its property for large ranges of parametric variations. This paper presents a new form of adaptive control used as a remedy for this issue, applied to the speed control of a multiphase multimachine motor drives system. The multimachines under investigation are a six‐phase and a three‐phase induction motors whose stator windings are connected in series and supplied by a single six‐leg converter and controlled using vector control approach. Fuzzy controllers are used to implement this type of control to increase its robustness. This leads to a fuzzy behavior model control (BMC). The results of the simulation confirm the validity and effectiveness of the control strategy proposed in both terms of performance and robustness (rotor inertia variations J1 = 5 J1nominal) of the provision of such an adaptive control for electrical drives with the two independently controlled machines.
