UML-RT Hybrid Control Strategy Approach of DC Servomotor Angular Speed by Using an Embedded Sliding Mode Control

The novelty of this paper is a hybrid approach for modeling and implementing a real-time control strategy of a dc Servomotor angular speed by using a sliding mode control module. The sliding mode controller is embedded in an open-loop control system structure with a dc Buck converter to stabilize and regulate the converter output voltage, despite the load current changes and unregulated power supply input voltage. The motivation of this approach is that the most of the physical objects from real life exhibit in a naturally way a hybrid structure, i.e. a switching continuous discrete variable structure over the time. In our proposed embedded control system structure it is the dc Buck converter that exhibits a hybrid dynamics, modeled and implemented by using an academic evaluation version of software package AnyLogic 6.7. In addition the proposed hybrid real time control strategy proved their effectiveness among the formal languages, and through their use in different real time control systems industrial applications.
