With the intensification of the global energy crisis and environmental pollution, the research and development of intelligent connected new energy vehicles have become a hot topic. This study focuses on the hierarchical optimization control method of intelligent connected new energy vehicles, aiming to achieve efficient energy management and utilization through dynamic programming algorithms. The study first constructed the dynamic model and energy $\text{flow}$ model of intelligent connected new energy vehicles, providing a theoretical basis for hierarchical optimization control. Subsequently, dynamic programming algorithms were used to optimize the energy management strategy, and the Bellman principle of reverse optimization was employed to search for the global optimal solution, in order to achieve rational allocation and efficient utilization of energy. The simulation experiment results show that the hierarchical optimization control method based on dynamic programming can significantly improve the fuel economy and emission performance of intelligent connected new energy vehicles, providing strong support for the intelligent and efficient development of new energy vehicles. This study not only has important theoretical value, but also provides useful reference for the practical application and promotion of intelligent connected new energy vehicles.

Ahstract- This paper presents a comprehensive investigation into the stability analysis and design conditions for quantizers to ensure the closed-loop stability of continuous-time linear quantized systems, under the conditions derived by the small-gain theorem. The study begins by deriving explicit bounds on the quantizer parameters required for maintaining system stability. Building on this foundation, an optimal controller is designed using the linear quadratic regulator (LQR) framework, providing an efficient data-driven control strategy. To further enhance the system's performance, an adaptive dynamic programming (ADP) algorithm, referred to as the hybrid iteration (HI) method, is developed. This algorithm effectively learns the optimal control policy by leveraging the trajectories of the quantized states and inputs, thereby addressing the challenges posed by quantization constraints. The proposed HI approach combines the advantages of adaptive learning and optimization, making it well-suited for continuous-time systems with limited information. The simulation results confirm that the ADP approach with the provided conditions not only stabilizes the quantized system but also achieves optimal control performance under the specified quantization conditions. This study offers valuable insights and a robust methodological framework for addressing stability and control challenges, with insights to be expanded to continuous-time nonlinear quantized systems, with potential applications in various engineering domains, such as networked systems, robotics and autonomous systems.

As the importance of optimizing resource management systems continues to grow, this paper focuses on the economic optimization of integrated systems through advanced computational models. First, we analyzed the economic feasibility of resource management systems without storage solutions, identifying that the configuration of power generation methods and dependence on external grids are key factors influencing economic outcomes. Subsequently, we introduced a dynamic programming model to optimize storage-integrated systems. By adjusting system constraints and solving linear programming projections, we significantly reduced the typical daily cost to 15,658 yuan. The optimization process, including charging and discharging strategies and the State of Charge (SOC) curve, was thoroughly visualized. Furthermore, considering fluctuations in demand and return on investment, a new coordinated configuration scheme was developed to optimize storage and resource acquisition under varying pricing conditions over time. This study highlights the crucial role of advanced optimization algorithms in enhancing the economic efficiency and reliability of future resource management systems, providing essential insights for the sustainable utilization of resources.

dynamic programming is a classical optimization technique that systematically decomposes a complex problem into simpler sub-problems to find an optimal solution. We explore the use of bio-inspired architectures to find the shortest path between two nodes in a graph using dynamic programming. We leverage dendritic computations, which are linear and nonlinear mechanisms in neuronal dendrites that allow to implement different computational primitives. We exploit two key mechanisms: 1) a dendrite acts as a delay line to propagate an excitatory post-synaptic potential to the soma, and 2) a feedback mechanism from the soma into the dendrites to control this delay. Our key ideas are the following. First, we model each node on a graph as a leaky integrate-and-fire (LIF) neuron, supporting the two dendritic mechanisms. We use a countdown counter to implement forward propagation of a delayed synaptic potential and eligibility trace-based feedback to update the delay by incorporating the cost of edges in a graph. Next, we formulate dynamic programming in terms of the time to the first spike in neurons. We breakdown the shortest path problem into sub-problems of finding the earliest firing times of neurons, and iteratively building the final solution from these smaller sub-problems by tracing backward. We implement this approach for several real-world graphs and show its scalability. We also show early prototyping on a Virtex UltraScale FPGA.

This study investigates the quality inspection and optimal decision-making in production processes using a dynamic programming algorithm. The primary objective is to develop a sampling inspection plan for components provided by suppliers, aiming to detect whether the defect rate of components is within the specified nominal value under different confidence levels (95% and 90%) while minimizing inspection costs. We propose a sampling model based on the Binomial Distribution and the approximate Normal Distribution to conduct hypothesis testing for defect rate detection. Additionally, a dynamic programming model is constructed to optimize decision-making in the production process, considering factors such as inspection costs, potential risk costs, and losses from defective products entering the market. The results show that the proposed models effectively balance inspection costs and quality control, leading to optimal decisions that maximize profit and minimize losses. Through Python-based simulations, we visualize the decision outcomes and validate the feasibility of the proposed approach.
