Abstract

Sliding mode control (SMC) is used to regulate the output power of an inductive power transfer (IPT) system with maximum efficiency tracking. Load variations and misalignment are the main factors that affect the output power and efficiency of the system. For that, SMC is used on the transmitter side to track the minimum input current in order to realize the maximum efficiency by regulating the duty cycle of the DC-DC boost converter connected to the power supply. However, SMC is used to access the desired output voltage by controlling the DC-DC boost converter connected to the load on the receiving side. Different control techniques that the SMC proposes are exploited on the sending and receiving side to achieve the desired output. SMC is also compared with the PI control technique. It introduces more efficiency and output power with variable load and coupling factor. Simulation results illustrate that the desired output voltage is achieved with different loads and different input voltages with 76% system efficiency. Moreover, the maximum efficiency has been achieved when the coupling factor is 0.7, while the maximum input power is achieved when the coupling factor is 0.1.

最大效率感应电力传输系统的滑模控制

滑模控制(SMC)用于调节感应功率传输(IPT)系统的输出功率，以实现最大效率跟踪。负载的变化和不对中是影响系统输出功率和效率的主要因素。为此，发射机侧采用SMC跟踪最小输入电流，通过调节与电源相连的DC-DC升压变换器的占空比来实现最大效率。然而，SMC通过控制连接到接收端负载的DC-DC升压转换器来获得所需的输出电压。在发送端和接收端利用SMC提出的不同控制技术来实现期望的输出。并与PI控制技术进行了比较。可变负载和耦合系数提高了效率和输出功率。仿真结果表明，在不同负载和不同输入电压条件下均能获得理想的输出电压，系统效率达到76%。耦合系数为0.7时效率最大，耦合系数为0.1时输入功率最大。
