sterowanie skalarne - Opis:
- Presently, motors that are installed in electrical drives require adjustment of speed or position or the both values simultaneously. It concerns not only simple drives of open-circuit speed control but also complex elevator drives and servo-drives that find ever-wider application. DC motors that initially dominated in the industry applications presently get replaced by AC motors as due to a huge development in the domains of power electronics and microprocessor technology the AC motor control is as simple and inexpensive as it is in the case of DC motors. The paper determines necessary conditions for a drive system that concern asynchronous motor control and follow from the need to ensure adequate torque overload capacity and a slip value. The requirements can be realized in drive systems by controlling amplitude and frequency of the feeding voltage. The following mathematical models of an asynchronous machine have been described: phase model, vector model and a model expressed in relative units. The models are considered as an introduction to further considerations on the control of asynchronous motors. Significant scalar control techniques for controlling speed and torque in such motors have been presented. A set of methods for the motor flux stabilization as well as a control with the rotor slip stabilization have been discussed.
