Global environmental changes, nuclear power risks, losses in the electricity grid, and rising energy costs are increasing desire to rely on more renewable for generation. Recently, most people prefer live work smart places like cities universities which integrating grid systems. The large part of these systems is based hybrid sources make management a challenging task. Thus, design an intellige...

A weighted summation of Integral of Time Multiplied Absolute Error (ITAE) and Integral of Squared Controller Output (ISCO) minimization based time domain optimal tuning of fractional-order (FO) PID or PIλDμ controller is proposed in this paper with a Linear Quadratic Regulator (LQR) based technique that minimizes the change in trajectories of the state variables and the control signal. A class ...

1-Department of Electrical Engineering, Amirkabir University of Technology, Tehran 1591634311, Iran * Corresponding author email: [email protected] ABSTRACT: A fractional order PID (FOPID) for a load frequency control (LFC) is presented in a three-area power system. FOPID controllers are designed the same way as PID controllers are, with the difference that FOPID controllers have five parameters...

Abstract—The fractional–order proportional integral (FOPI) controller tuning rules based on the fractional calculus for the cascade control system are systematically proposed in this paper. Accordingly, the ideal controller is obtained by using internal model control (IMC) approach for both the inner and outer loops, which gives the desired closed-loop responses. On the basis of the fractional ...

Abstract In this paper, an interval type-2 fuzzy fractional order PID controller (IT2F-FOPIDC) based on particle swarm optimization is proposed. The proposed has two adjustable degree of freedom parameters, so the control range parameters becomes larger and can controlled object more flexibly. Aiming at difficult problem many tuning, paper introduces algorithm to optimize parameters. avoid prob...
