摘要：

Energy balance control uses electromagnetic energy conversion for system control. Energy balance control can provide coordinated, unified control of multiple goals that conditional controllers cannot provide by replacing the voltage and current with the energy into the energy storage elements. A system model is used to determine the control variable from the energy or power control target to improve the control system. However, the energy balance control method does not have either a steady state error analysis or a method to reduce the steady state error and there is no global stability analysis. This paper presents a steady-state error and global stability analysis for energy balance control. The three existing energy balance control methods have equivalent forms of the outer loop sliding mode surface and the inner loop controller. These are used to quantitatively analyze the steady-state error. A global Lyapunov stability analysis is provided along with a method for setting the energy balance control parameters. © 2020, Tsinghua University Press. All right reserved.
