An indirect adaptive neuro-fuzzy speed control of induction motors

This paper presents an indirect adaptive system based on neuro-fuzzy approximators for the speed control of induction motors. The uncertainty including parametric variations, the external load disturbance and unmodeled dynamics is estimated and compensated by designing neuro-fuzzy systems. The contribution of this paper is presenting a stability analysis for neuro-fuzzy speed control of inducti...

Damping analysis of sub-synchronous resonance (SSR) in a wind farm based on DFIG in a series compensated network

The effect of wind generator on sub-synchronous resonance (SSR) is being interested by increasing penetration of wind turbine in power systems,. Purpose of this article is to analyze SSR in a wind farm based on doubly fed induction generator (DFIG) which is connected to compensating series grid. A dynamic model for analysis of induction generator effect and Torsional Interaction (TI) has been u...

Gravity compensation in accelerometer measurements for robot navigation on inclined surfaces

Accelerometers are used in most robot navigation systems as sensors for robot speed and localization. Normally, these accelerometers sense the body acceleration, which is integrated to determine the robot velocity, and cumulatively the robot position relative to the starting position. When the robot is moving on a horizontal surface, the computed speed will in general reflect the actual robot s...

Designing voltage tunable single and multi-channel optical filter with 1DDPC nano-structure

An electro-optic tunable single and multi-channel optical filter based on one-dimensional defective photonic crystal (1DDPC) structure is proposed. A couple of externally tunable defects in arrangement of (AB)5D1(BA)D2(BA)5, where A and B are dielectric materials, D1 and D2 are the tunable defects are used. The defects are composed of the ferroelectric LiNbO3 crystals and two pairs of thin Ag l...
