In Industrial area one 11KV feeder feeds a static power converter fed DC motor load of variable power and some usual loads i.e domestic to industrial loads. Faults at DC motor load affect the other feeder loads. The L-G and L-L faults followed by open conductor fault on DC motor load effect the other feeder loads. This paper deals with the voltage dips and correction using the DSTATCOM, a custo...

A model based fault detection and diagnosis technique for DC motor is proposed in this paper. Fault detection using Kalman filter and its different variants are compared. Only incipient faults are considered for the study. The Kalman Filter iterations and all the related computations required for fault detection and fault confirmation are presented. A second order linear state space model of DC...

This paper presents fuzzy and conventional performance of model reference adaptive control(MRAC) to control a DC drive. The aims of this work are achieving better match of motor speed with reference speed, decrease of noises under load changes and disturbances, and increase of system stability. The operation of nonadaptive control and the model reference of fuzzy and conventional adaptive contr...

This paper describes an expanded system for a servo system design by using the Loop Shaping Design Procedure (LSDP). LSDP is one of the H design procedure. By conducting Loop Shaping with a compensator and robust stabilization to satisfy the index function, we get the feedback controller that makes the control system stable. In this paper, we propose an expanded system for a servo system design...

The aim of this work is to design and simulate an armature and field control systems using state feedback controller based on bacterial foraging optimization (BFO) technique for controlling the speed of separately excited dc motor (SEDM). The controller's performances have been optimized based on social foraging behavior of Escherichia (E. Coli) bacteria. The state feedback controller's paramet...
