The suspension system is an important unit that affects vehicle performance, including handling stability and riding comfort. In order to improve performances, a novel robust optimal control strategy for the active in vehicles proposed. To handle parameter uncertainties external random disturbances, proposed designed by using combination of linear quadratic regulator (LQR) sliding-mode control. First, nominal model without uncertain parameters performance index given, initial controller LQR...
This article focuses on the practically predefined-time adaptive fuzzy quantized control for nonlinear stochastic systems with actuator dead zone. Fuzzy logic are employed to approximate uncertain functions. A novel scheme is proposed, which can help reduce parameters and increase robustness of closed-loop system. Taking quantization zone in link into account, a part used estimate compensate disturbance, respectively. In addition, under reasonable assumptions, complexity Lyapunov function...
Abstract Predicting the crystal structure is essential to address reliance on serendipity for facilitating discovery and design of high‐performance high‐entropy oxides (HEOs). Here, three classic algorithms‐based machine learning models predict HEOs are successfully established analyzed by combining five metrics, XGBoost classifier shows excellent accuracy robustness with ACC F1 scores up 0.977 0.975, respectively. SHAP summary plot indicates that anion‐to‐cation radius ratio ( r A / C ) has...
An improved model of the active suspension system is proposed. Compared with existing system, dynamics a hydraulic actuator in fully considered proposed model.

Carbon fibre–reinforced plastic rods–reinforced and Kevlar-reinforced silicone rubber matrix composite designed, fabricated, tested, utilized the demonstrator wing. design has achieved satisfactory wrinkle onset angle (>50°) without applying pre-tension or pre-stretch, low in-plane stiffness allows of 1 m 2 to 30° under 30 kg actuating force, designable out-of-plane stiffness, considerable...
To achieve more precise positioning of the electronic throttle plate, a nonlinear backstepping tracking control strategy is presented in this paper. In contrast to existing schemes for throttles, input saturation and unknown external disturbances are explicitly considered design. The difficulties controlling an include strong nonlinearity spring friction as well disturbance. particular, valve plate angle adjusted by voltage driving motor, limited certain range. Therefore, problems exist...
In recent years, the research on control strategy of three-phase grid-connected inverter has attracted significant attention. Proportion integration (PI) method is widely utilized to inverter. However, coordinate transformation an essential and complex step during design process conventional PI controller. It difficult implement in practice due transformation. The proportional-resonant (PR) proposed, where controller replaced by PR a simple structure as can be neglected. order improve power...
In modern vehicles, electronic throttle (ET) has been widely utilized to control the airflow into gasoline engine. To solve difficulties with an ET, such as strong nonlinearity, unknown model parameters and input saturation constraints, adaptive sliding-mode tracking strategy for ET is presented. Compared existing strategies constraints parameter uncertainties are adequately considered in proposed strategy. At first, nonlinear dynamic of described. According dynamical model, method...

Based on backstepping design technique, new controller developed for throttle....
Microgrid has been extensively applied in the modern power system as a supplementary mode for distributed energy resources. The microgrid with wind is usually vulnerable to intermittence and uncertainty of energy. To increase robustness microgrid, storage (ESS) necessary compensate imbalance between supply load. further maximize economic efficiency system, level control desired be optimized when it integrated utility grid. Aiming at aforementioned problem, this paper comprehensively analyzes...
The stress corrosion cracking behaviors of micro-arc oxidized AZ31 magnesium alloy were studied by using the slow tensile test in air and 3.5 wt.% NaCl solution. Results showed that compared with substrate, susceptibility specimens was obvious improved apparently solution, due to good resistance after coating treatment. In addition, regardless treatment, it mixed fracture cleavage had no direct effect on mechanism alloy. It closely related nature material environment servicing.
