The low speed system’s hardware setup is composed of a permanent dc motor, driving circuit, servo amplifier (PWM), a mechanical frame as an inertial load, interface circuit (A/D and D/A), an encoder for position sensing, and a personal computer (PETIUM I 133) is used as the programming environment, using Borlandc31 as programming language for the [...]
Two advanced control strategies of adaptive friction Compensation For DC servomotor are presented in this paper, the first is used for The direct on-line friction compensation in the velocity control system, The second is making use of an adaptive inverse neural network controller In the position control system. Both are composed of an adaptive Compensator [...]
The UCC3626 motor controller device combines many of the functions required to design a high-performance, two- or four-quadrant, threephase, brushless dc motor controller into one package. Rotor position inputs are decoded to provide six outputs that control an external power stage. A precision triangle oscillator and latched comparator provide PWM motor control in either voltage- [...]
