Npc Inverter Supplied Induction Motor Drive With Anfis Controller By Passivity Based Model Predictive Control

Abstract

In this presented paper the neutral point clamped (NPC) inverter supplied induction motor (IM) by the finite set model predictive control (FCS-MPC) has acquired great consideration now a days, due to its fast dynamics and low switching frequency. Anyhow, the functioning mainly based on the accurate measurement and variables that verifies the control loops and feedback paths. In addition to that, this FCS-MPC challenges a huge number of resources to execute the extensive search, which shows that the calculation load raises exponentially with the enhancement in the shifting states. Pointing at correcting the toughness following the criteria of inevitable testing of noises and parameter fluctuation along with decrement in the computational burden, the strategy of passivity based model predictive control (PB-MPC) has been proposed in this paper. If the standard system is taken into account, the PB-MPC has the identical behavior as the FCS-MPC. In the case of actual implementations, in the place where the disturbances and noises do influence these methods, the PB-MPC surmounts FCS-MPC because of power modelling and damping injection transmitted from the passivity based control (PBC) that assures the asymptotic stability. For validating the stability the Lyapunov function is composed in this presented scheme. Here the proposal of PB-MPC with the speed comparison by the proportional integral controller has been replaced by the anfis controller both the simulation results are compared successfully through the MATLAB software.
