Query: Optimization of PI Coefficients in DSTATCOM Nonlinear Controller for
  Regulating DC Voltage using Particle Swarm Optimization   Non-linear controller is preferred to linear controller due to non-linear
operation of DSTATCOM. System dynamic can be improved by regulating and fixing
the capacitor DC voltage in DSTATCOM. The nonlinear control is based on exact
linearization via feedback. There is a PI controller in this system to regulate
DC voltage. In conventional scheme, the trial and error method is used to
determine PI values. Exact calculation to optimize PI coefficients can be
carried out to reduce disturbances in DC link voltage and thus, in this paper,
Particle Swarm Optimization is applied. As a result, Capacitor voltage tracks
the reference values which have less vibration than conventional status. Both
trial and error method and PSO are implemented. A set of corresponding diagrams
achieved by these two methods are offered to demonstrate the effectiveness of
new method. Optimizations and Simulations are worked out in MATLAB environment.
