Event triggered non-inverting chopper fed networked DC motor speed synchronization

Abstract

PurposeThis paper aims to provide a new approach to address the problem of reaching the synchronous speed in the network connected multiple motors. Design/methodology/approachPractically, all the control approaches require continuous monitoring of the system thereby consuming extra energy. The method proposed in this paper uses an event-based approach with the multi-agent system (MAS) consensus control alongside with linear quadratic regulator control, thus saving a larger amount of energy. The proposed system is developed by using non-inverting buck boost chopper to provide necessary electrical power for the direct current motor, hence creating a single agent of bigger MAS with identical dynamics. The system stability is formulated by using Lyapunov stability theory. The proposed system is simulated via MATLAB. FindingsThe acquired simulated results validate that the proposed methodology and the multi-motor system worked successfully, thereby achieving common speed, i.e. consensus. The proposed system also validates the energy-saving concept. Practical implicationsPresently, the multiple motor synchronous speed system found application in paper-making machines, textile printing machines, offset printing, etc. The proposed study will contribute greatly to the existing methodologies and overcome their deficiencies by making the system more flexible and error-free due to the presence of network connectivity. Originality/valueThe system is simulated to verify theoretical concepts.

Leader-Follower Multimotor Speed Coordination via Adaptive Fuzzy Multiagent Consensus Scheme

“…e stability of the system is verified via the Lyapunov theorem with respect to the single agent such that if it is controllable and observable then the rest of the system reaches synchronous control of the motors. Similar problem is also addressed by the authors in [29,30]. us, inspired by the abovementioned research, in this study, a new multimotor system is presented utilizing a predesigned fixed and undirected network to interconnect the agents in a leader following MAS architecture, which is, in this case, noninverting chopper-driven DC motor.…”

Distributed Event-Based Control of Hierarchical Leader-Follower Networks with Time-Varying Layer-To-Layer Delays

“…Suppose that Assumptions 1, 2 and 3 hold. Consider the HLFN Equations (1) and (2) with control, (26) and (27), the consensus problem can be solved if:…”

“…The paper [22] showed that event trigger control has lower communication times and controller update times and better control effect than periodic sampling control on the premise of completing control tasks. The event-based control technology attracted much attention because of the characteristics of resource saving, and related research also achieved more results [23][24][25][26][27][28][29][30]. However, the consensus problem of HLFNs remains unsolved.…”

Modeling, Design and Control of Speed DC motor using chopper

“…A high-performance motor drive system will have fast response times and accurate tracking of dynamic speed commands [6]. DC drives have commonly employed in applications that require variable speed control, reliable speed regulation, regular starting, reversing and effective braking [7].…”
