Abstract
Usually proportional-integral (PI) controller tuning
rules are derived based on linear models of the plant or process,
without taking nonlinearities into account. Hence, the best
control performance cannot be ensured. This paper presents
optimal tuning method based on more accurate nonlinear models
of the three-phase voltage regulator converter. This nonlinear
model is considered as objective function with input arguments of
proportional gain and integral gain, besides its output is the
integral of time multiply squared error (ITSE) of PI controller.
The measure of ITSE error is used to depict the system
performance i.e. the fitness function. Using optimization method
of particle swarm optimization (PSO), the performance index of
ITSE is minimized to zero by finding the optimal PI tuning. The
fitness function evaluates the performance of a particle to
determine whether the best fitting solution is achieved.
Simulation results are provided based on MATLAB Simulink.
