Abstract
In this article, a new proportional, integral, derivative, and acceleration (PIDA) controller for an automatic voltage regulator power system is presented. The controller parameters are designed by considering as an optimization with minimization of square error using bat algorithm. The response of the bat algorithm optimized PIDA (BA-PIDA) controller are observed and compared to the controllers in the literature. The superiority is validated in terms of performance indices (ITAE, IAE and ISE).
Highlights
The application of control system in the design of an efficient and economic controller is always a challenge to control engineers
In 1996, Jung and Dorf proposed a new structure of controller and termed as proportional- integral-derivative and acceleration (PIDA) controller [2]
Each pulse generated by a micro bat may last only for 8 to 10 milliseconds with a frequency ranging from 25 kHz to 150 kHz, which corresponds to the wavelengths of 2 mm to 14 mm [15]
Summary
The application of control system in the design of an efficient and economic controller is always a challenge to control engineers. In 1996, Jung and Dorf proposed a new structure of controller and termed as proportional- integral-derivative and acceleration (PIDA) controller [2]. It consists of three numbers of zeros and poles but two poles may be neglected in the design process. Dal-Young et al, 2001, highlighted the higher overshot during the rise time while designed PIDA controller with analytical method. It were mitigated using pre-compensator to PIDA in ac motor control in [7].
