Voltage control of DC-DC Three level Boost converter using TS Fuzzy PI controller
For power electronics engineers, this is an incremental application of existing fuzzy control methods to a specific converter topology.
The paper proposes a TS Fuzzy PI controller for a DC-DC Three-level Boost converter, demonstrating through simulations that it provides flexibility, disturbance rejection, and performance across a wide operating range.
Appropriate control contributes essentially in the design of efficient DC-DC converters. With this intention, a study deals with the synthesis of a controller for DC-DC Three-level Boost converter (TLBC), has been addressed. The studied TLBC, known as nonlinear system, has been locally modeled using transfer function models. For instance, PI controllers were designed using the local models, and then they were combined using Takagi-Sugeno fuzzy (TSF) approach to form a TSF-PI controller. Simulation tests show the flexibility of the proposed controller, its rejection capability to different disturbances, and its ability to achieve the performance specification overall the wide operating range of the system.
