In this paper, the hysteresis current controller is modeled with PWM rectifier for stability analysis and design of dc link PI controller. The results of linear model are compared with the detailed simulation results during starting period of the rectifier. The stable operating ranges of system parameters like hysteresis band width, boost inductance, dc link capacitor and sampling frequency are verified by the detailed dedicated simulation program in Matlab/Simulink interlinked to TMS320F2812. The results has shown that the linear model correctly predicts the stability of the system and provides the feasible solution for PI controller parameters from Routh -Hurwitz criteria. The experimental records during the starting and load changing are also given.

Equivalent linearization of 2-way fuzzy adaptive system under nonparametric uncertainty and inconsistency
Gurkan, E; Banks, SP; Erkmen, Aydan Müşerref; Erkmen, İsmet (2002-09-18)
Our aim in this paper is to design a 2-way fuzzy adaptive controller for a flexible robot arm and to analyze the stability of this controller using describing function technique. The 2-way fuzzy adaptive system is used in order to model the nonparametric uncertainties and inconsistencies present in the nonlinear system. The use of intuitionistic fuzzy sets in the 2-way fuzzy adaptive structure makes it possible to model such uncertainties. The proposed architecture is used as a controller for a flexible-joi...

Adaptive Nonlinear Control Combined With Unscented Kalman Filter for Permanent Magnet Synchronous Motor Fed by AC/DC/AC Converter
Titaouine, A.; Taibi, D.; Bennis, O.; Benchabane, F.; Boumaraf, R.; Yahia, K. (2011-09-10)
In this paper, a adaptive non-linear controller is presented for permanent magnet synchronous motor (PMSM) sensorless drives. The adaptive non-linear controller is designed based on an input-output feedback linearization control technique. The unscented Kalman filter is used to estimate the speed, position and load torque. The PMSM is fed by an indirect power electronics converter. This indirect converter is controlled by a sliding mode technique that enables minimization of harmonics introduced by the line...
