Comprehensive analysis and response of closed loop cbbctpnli system with pi and flc

Abstract

The industrial drive is normally using three-phase induction motor, since they need high speed –torque performance operations. The speed control is normally in open loop. However, these open loop drives are not giving good performance. The closed controller is playing a role in the design of any closed loop system. PI controller is the best conventional controller. The fuzzy and neural based controller is better than PI controller for many applications. Hence, in this chapter, a fuzzy logic based closed loop speed control of motor is investigated. In addition to speed control, the current controls are pre-requisite for providing the smooth speed-torque characteristics. In this paper a 3Ф five-level DC to DC converter five-level CHB-MLI fed variable speed motor with proportional integral and fuzzy logic controller are modeled and investigated using MATLAB/Simulink. The analysis is made with various modes of operation of motor drive. The FPGA SPARTAN-3 controller based experimental setup is realized and tested for the proposed HCC and FLC speed controller. The experimental results are conforming simulation results and prove the FLC performance against speed and HCC.
