| Abstract [eng] |
Currently in the majority of automatic control systems are the devices that improve the qualitative characteristics of these systems. These devices – controllers. Controllers form the object's control law, so using controllers is possible quality parameters of the original control system to place closer to the desired characteristics of the system. The aim of this work is the investigation of the dynamical quality improvement method of the electromechanical velocity stabilization system based on the variable structure velocity controller. The MATLAB/SIMULINK model of the electromechanical speed stabilization system with variable structure controller has been created. According to the quality indicator – settling time, it has been determined the control law switching parameter dependence on the static load and the command input ensuring the best dynamical quality of the electromechanical speed stabilization system. The Luenberger observer has been applied for the static load estimation during the transient regime of the electromechanical speed stabilization system. The obtained results are universal and have been successfully applied for the DC electric drive model simulaiting the automatic control law change from the proportional (P) to the proportional integral (PI) using Lookup Table. |
