Abstract Compared to lithium-ion batteries, redox-flow batteries have attracted widespread attention for long-duration, large-scale energy-storage applications. This review focuses on current and future directions address one of the most significant challenges in energy storage: reducing cost battery systems. A high priority is developing aqueous systems with low-cost materials high-solubility redox chemistries. Highly water-soluble inorganic couples are important technologies that can...
Abstract In recent years, the development of microgrids has driven reform electricity market, breaking monopoly traditional power grids and promoting healthy market. However, stability is significantly impacted by integration various energy sources numerous users. This study explores application an intelligent dynamic programming algorithm based on deep neural network algorithm, combined with adaptive programming. Subsequently, real-time generation control (IRPGC) obtained introducing...
For small target objects on fast-moving conveyor belts, traditional vision detection algorithms equipped with conventional robotic arms struggle to capture the long and short-range pixel dependencies crucial for accurate detection. This leads high miss rates low precision. In this study, we integrate EMA (efficient multi-scale attention) algorithm c2f (channel-to-pixel) module from original YOLOv8, alongside a Faster-Net designed based partial convolution concepts. fusion results in...
Loop-shaping H∞ controllers are designed for both stable and integrating processes. typical industrial processes have a PID structure interpretation. Further, if the precompensator is carefully chosen, design indicator will be independent of plant constants. This fact leads to derivation direct relation between controller parameters constants, results can viewed as new tuning rules The main contribution that obtained using one parameter which reflects trade-off stability robustness time...
To promote the intelligent vehicle safety and reduce driver steering workload, stackelberg game theory is adopted to design shared control strategy that takes neuromuscular delay characteristics into account. First, a framework with adjustable driving weight proposed, coupling interaction model considering constructed by using theory. Moreover, driver-automation optimal deduced theoretically when equilibrium reached. Finally, simulation virtual tests are carried out verify superiority of...
The shape control of probability density function (PDF) is an important subject in stochastic systems. PDF-shaping study has ranged from linear systems to non-linear In this paper we present a technique which useful for class Controlling the PDF requires designing controller make state follow goal PDF; it actually determine gains controller. As know, stationary variable equivalent solution Fokker–Planck–Kolmogorov (FPK) equation arising system driven with Gaussian white noise. After...
To deal with the sideslip angle caused by current disturbances or transverse motion for path following of under-actuated ships, a nonlinear observer established an exponential function is introduced in backstepping approach which converts into heading control. Then, model predictive control (MPC) method used as controller, addressing rudder optimization. A linear extended state technology was exploited to estimate yaw rate, external disturbances, and internal uncertainties, could avoid...

Peak component stresses can be obtained from models, which helps to design converter. In this paper, operational principles topology DCM introduced simple accurate expressions describing...
Like the one used in industrial applications, motor drive system for electric vehicle (EV) is composed of a three phase inverter, controller, and sensor system. The difference that EV packaged with much higher power density its operation status changes frequently. A direct consequence key components such as insulated gate bipolar transistor (IGBT), capacitor well insulation bearings endure harsh thermal stress. It these which dominantly affect life <sup...
Generally, the overmodulation techniques for space vector pulse width modulation (SVPWM) inverters need store lots of date in controller beforehand, which makes a huge memory while control resolution is not perfect. Based on amplitude reference voltage and vertex vectors, this paper presents novel digital over-modulation strategy SVPWM inverters, can manage transition from linear range to six-step operation smoothly. With avoiding necessity stored data implementation, simple very suitable...
