Chaotic Speed Synchronization Control of Multiple Induction Motors Using Stator Flux Regulation

This paper presents and implements a new control approach to synchronize the chaotic speed of multiple induction motors. The direct torque control (DTC) using the stator flux regulation (SFR) method is the key for the chaotic speed control. Additionally, a nonlinear control approach, namely the adaptive time-delayed feedback control, is proposed to regulate the reference torque for the SFR-based DTC unit. By using the proposed control scheme, multiple induction motors can achieve a synchronized chaotic speed within a controllable boundary.
