BERZOY, Alberto  and  STREFEZZA, Miguel. Shunt fuzzy PI control compensating a line current PI control response in a three phase rectifier. Rev. Fac. Ing. UCV [online]. 2013, vol.28, n.1, pp.59-64. ISSN 0798-4065.

This work presents the simulation of a fuzzy PI control connected in shunt topology with a line current mistuned PI control. The goal of the system is to correct the line current in a three phase rectifier. The fuzzy PI control is a zero-order Takagi-Sugeno Fuzzy Inference System (FIS T-S) connected in parallel with a classical mistuned PI control to compensate its response and achieve power factor correction. The simulations were carried out in an Analog Devices 21061 digital signal processor (DSP).

Keywords : Three phase rectifier; Fuzzy control; Takagi-Sugeno Fuzzy inference system; Power Factor; Proportional- Integral control.
