The digital control power supply has been widely used by virtue of its many advantages. However, it may cause limit cycle oscillations due to quantization in the feedback loop when the switching frequency is high. This paper presents an analytical model of buck converter using state space average method and derives the equilibrium expression in steady state, and the requirement for DPWM resolution...
In this paper, an LLC resonant converter design methodology for battery charger based on mode analysis is presented. The accuracy of DC gain curve obtained by mode analysis is much higher than that by FHA. Conduction loss and switching loss can be minimized by reasonably configuring charging trajectory on the mode distribution map. ZVS and ZCS can be realized during whole charging process. Finally,...
This paper studies the problem of transfer learning in the context of reinforcement learning. We propose a novel transfer learning method that can speed up reinforcement learning with the aid of previously learnt tasks. Before performing extensive learning episodes, our method attempts to analyze the learning task via some exploration in the environment, and then attempts to reuse previous learning...
People consistent labeling across multiple cameras in the scene with multiple planes ground is a challenging task. We propose a simple but effective method to cope with it. In our method, camera calibration is not needed, the scene is not constrained to a planar ground and the cameras can be set at any oblique angles. The homography induced by the plane at a certain height parallel to the lowest groune...
