Fuzzy logic – based control schemes have been selected as a perfect replacement for traditional regulators e.g. PI and PID due to their undeniable advantages such as no need of exact model and only depending upon expert’s experiences. It should be prominent in use from these fuzzy logic structures the PI-like Mamdani and Sugeno – based inference models have been widely used in academic studies. This paper focuses on creating a theoretical analysis and comparison for both of them. A typical case study regarding the speed control of a hydropower plant against various load changes is taken into consideration in order to demonstrate the applicability of the proposed control strategy. This is considered to be one of the most crucial control strategies for operation and stability of a hydropower plant. It was found that a lot of promising simulation results obtained by using Matlab/Simulink software when applying the PI-like Sugeno fuzzy logic controller are superior to those of the existing counterparts such as conventional PID and Mamdani – based one in dealing with the generator’s speed control problem presented in this study

Fuzzy logic -based control strategies have been considered to be a feasible replacement of conventional PID regulators due to their dominant advantages. One of the most outstanding characteristics of a fuzzy logic -based control scheme is that the system might not require full parameters as well as an exact model; instead, it depends only upon experts' understanding about the control plant. This paper proposes the design of a novel PID -like Sugeno -based fuzzy logic controller. With a significant set of fuzzy rules and four scaling factors tuned by a proper optimization method, such a Sugeno -based inference model is completely able to solve a lot of complicated control problems. A typical control issue concerning the speed stability of generators in hydropower plants applying the studied fuzzy logic controllers will also be taken into consideration. Promising simulation results obtained demonstrate effectiveness and applicability of the control methodology proposed in this study.

In an electric power grid, Load-Frequency Control (LFC) plays a crucial role as it aims to maintain the system frequency at a nominal value, 50 or 60 Hz, by minimizing the effects of load changes. However, a modern power system is currently characterized by a huge number of nonlinearities and uncertainties, making control methodologies much more challenging. Among them, the nonlinear features of Governor Dead-Band (GDB) and Generation Rate Constraint (GRC) strongly affect the accuracy and performance of LFC applied to a power network. This study focused on designing an applicable and efficient LFC by proposing a novel Sliding-Mode Control (SMC) scheme. The traditional SMC can successfully solve several nonlinear control problems, and in case of having a reasonable adjustment, it is completely suitable to design the LFC strategy. The modified SMC, integrated with an effective optimization technique, i.e., Particle Swarm Optimization (PSO), can dramatically improve the performance of LFC. This paper presents numerical simulation results implemented in MATLAB/Simulink to demonstrate the feasibility and effectiveness of the proposed control strategy.
