Speed Performance Improvement of DC Motor using Fuzzy Based MPPT fed from Solar System

Solar Energy utilization is very less in compare to availability of resource and PV technology is widely used for many application. Solar energy as main source of supply, for controlling the load voltage FLC logic is implemented, which is one of the best utilized tool of Artificial Intelligence (AI). Solar output is controlled in precise manner with the help of FLC controller in adjoining with buck boost converter, by which we controlled MPPT of solar PV output. Being commonly used industrial drive, DC Motor is used as inductive load. In this article, FLC is used in comparison to PI Controller for control the speed performance of a separately excited DC Motor. Power quality issues are considered to reduce the burden in the isolated PV system. Starting torque with a smooth speed up is achieved in DC Motor which further improve power quality and reduce initial transient. For efficiently regulating & controlling the speed of DC Motor here control strategy implemented. Results confirm that the FLC improved the rise time by 65.401ms & overshoot limited to 0.5% in comparison to PI controller.
