Variable structure approach for brushless servo motor control.

Apply Estimated Model Based Variable Structure Control to Brushless DC Motor Control

The variable structure control theory based on estimated model is proposed in this paper. The ARX theory is applied to figure out the parameters of estimated model of unknown system on-line. According to the estimated, the variable structure control can be developed and implemented to this unknown system like known system. The equivalent controller of variable structure control rule will work t...

Simulation Approach for Sliding Mode Control of Induction Servo Motor

The main objectives of this paper is aimed to control the position of a field oriented Induction Servo motor drive for a given reference input signal in a very efficient way and to compare the two control schemes using Matlab/Simulink. To determine a PI control system which is insensitive to uncertainties, including parameter variations and external disturbances in the whole control process. To...

Variable structure methods in hydraulic servo systems control

In the general framework of hydraulic servo systems, this paper addresses the problem of position control in the presence of important friction nonlinearities. The accent falls on the variable structure methodology, as we try to use its intrinsic robustness properties. Several friction observers, including the one based on a variable structure approach, were incorporated and tested in an accele...

Robust Control of Servo DC Motor: LMI Approach

The robust servomechanism problem consists in finding an LTI controller for the plant so that: (i) the resultant closed-loop system is asymptotically stable, (ii) asymptotic tracking occurs, and (iii) condition (ii) holds any arbitrary perturbation in the plant model (parametric uncertainty or dynamic uncertainty, including changes in model order) that do not cause the resultant closed-loop sys...
