Design of Proportional Integral Controller for Level Control of Single-Tank System Using Sine-Cosine Algorithm

Abstract

In this research, PI controller is planned for controlling the level of single-tank system by using sine-cosine algorithm (SCA). Integral-square-error (ISE) of unit step be abated for obtaining best controller parameters. Alpha and Beta tables are used for calculating the ISE. Sine-cosine algorithm is used for abating the ISE to find the best parameters of PI controller. Results attained using SCA specify that the performance of the PI controlled structure can be improved significantly. Statistical analysis and time domain simulations are given to confirm the proposed controller.
