Robust Anti-disturbance Control for Dynamic Wireless Charging System of AGV with Constant Output Voltage Regulation
摘要
Automated guided vehicles (AGVs) are increasingly used in industrial production and daily life, offering significant benefits such as enhanced productivity, support for green development, and improved quality of life. However, their limited energy storage capacity restricts their broader adoption. Dynamic wireless charging (DWC) technology addresses two major concerns: prolonged charging times and range anxiety by enabling continuous charging during AGV operation. Despite these advantages, DWC systems are challenged by various disturbances, including fluctuations in mutual inductance, load variations, nonlinearities, unmodeled dynamics, parasitic resistance, parametric drift, and electromagnetic interference. Unlike static wireless charging systems, DWC systems face rapid and continuous changes in mutual inductance between the transmitting and receiving coils, leading to significant output voltage fluctuations. To address these challenges, several advanced robust anti-disturbance control schemes have been developed to ensure a stable, continuous power supply for AGVs. These control strategies offer several advantages, including reduced sensor costs, enhanced anti-interference capabilities, improved noise suppression, and stable voltage regulation. The proposed control methods play a critical role in promoting the widespread adoption of DWC systems, effectively mitigating the range anxiety challenges faced by AGVs.
