| Summary: | The Automatic Voltage Regulator (AVR) has
been developed with the automated purpose of maintaining
voltage stability for synchronous generators. This structure is
often controlled by installation of the Proportional-Integral-
Derivative (PID) controller. Contemporary heuristic
approaches further inspired scholastic pursuits which advocate
numerous innovative PID-based optimization techniques.
Nevertheless, offsetting of such benefits and precision on
disproportionate theoretical outcome by existence of modelling
errors and uncertainties has necessitated continuous effort in
tuning the PID controller. Considering possible jeopardizing of
operational effectiveness and consistency through manualized
optimization of controller’s parameters, the current study
essentially secured the effectiveness of a PID-controlled AVR
system through online tuning. The adopted indirect design
technique emphasized exclusive optimization of frequency shift
constant of a formerly optimized PID controller as employed
within an AVR structure. Enhancement of control efficacy and
operation is achievable through revised parameters in the
earlier PID controller from an updated frequency shifted
constant. Compatibility of the introduced optimization
mechanism was contrasted against parameters of the formerly
optimized PID controller on the account of maximum
sensitivity, gain and phase margins. Conducted simulations
demonstrate substantial enhancement in performance of AVR
structure with PID con-troller through parametric refining of
the introduced mechanism. |
