“…The time response of the system in (12) to a unit step input is given in (13). If "t r " is the required rise time for the design, it is defined as the time required for the response to rise from 10% to 90% of its final value and the resulting expression for K D is given by (14).…”

“…With the help of precise data for the system in all these cases, optimum performance is observed. However, in the absence of precise data, the initial requirements such as initial weight for the neural network, trails in ant colony algorithms [12], norms in multi-objective optimization, population size in swarm optimization [13] and rules in the fuzzy technique are not precisely set; therefore, the control process fails. To calculate the analog controller parameters for the excitation systems and to operate it within the protection limits, a method was proposed in [14] to make the performance indexes of the designed controller to comply with the IEEE standard but the method is only suitable for analog controllers.…”

The digital excitation control system (DECS) used for brushless synchronous generators has recently become popular owing to its ease of operation and flexibility to manage the operating parameters to achieve good maintenance of the output terminal voltage at the rated value. The latest industrial digital automatic voltage regulator (AVR) is used in the forward path of DECS. This paper addresses the issues of the DECS that are responsible for deviating the terminal voltage from the rated value and consequently making the power system unstable. A solution to the issue is provided using a new method of tuning the PID controller that eases the impact of discretization on the terminal voltage and keeps the DECS compatible with industrial standards. The controller designed in this way will be useful to maintain the terminal voltage of the synchronous generator to enhance the stability of the power system to which many renewable energy sources are interconnected. The proposed method improves the performance of the excitation control system by reducing the overshoot from 75% to 16%. The simulation results are presented using an industrial standard model of the excitation control system to demonstrate and compare the performance of the existing with the new digital excitation system. The newly designed controller was tested and validated using the "hardware in the loop" (HITL) technique.
