Speed tracking and synchronization of multiple motors using ring coupling control and adaptive sliding mode control

Area of Science:

• Electrical Engineering
• Control Systems Engineering
• Robotics

Background:

• Precise speed tracking and synchronization of multiple motors are critical in various industrial applications.
• Existing control methods often struggle with uncertainties and chattering, limiting performance.

Purpose of the Study:

• To develop a robust control strategy for achieving accurate speed tracking and synchronization in multi-motor systems.
• To address limitations of conventional control approaches by incorporating adaptive sliding mode control.

Main Methods:

• An adaptive sliding mode control (ASMC) technique was integrated into a ring coupling synchronization control structure.
• An adaptive law was employed to estimate uncertainty bounds based on the Lyapunov stability theorem.
• Performance was evaluated through comparisons with parallel control, relative coupling control, and conventional PI control.

Main Results:

• The proposed ASMC scheme effectively stabilized speed tracking for individual motors.
• Synchronization errors and speed tracking errors converged to zero, demonstrating precise motion coordination.
• The adaptive law successfully minimized control effort and attenuated chattering, enhancing system robustness.

Conclusions:

• The developed adaptive sliding mode control approach offers superior performance for multi-motor speed tracking and synchronization.
• This method provides a robust and effective solution for complex motor control systems.
• Simulation results validate the proposed scheme's effectiveness and superiority over traditional methods.
