This article focuses on the fast position tracking problem for permanent magnet linear motor (PMLM) system under a chattering-reduced sliding mode control signal. To this end, class of globally nonsingular (SMC) laws, called logarithmic (LnSM) control, is proposed in article. Using natural logarithm function, high gain established at equilibrium reduced-order system, which leads to higher precision and faster local convergence rate than those some classical SMCs. In addition, super-twisting...
This article's primary motivation is to propose a nonsingular and continuous terminal sliding-mode (TSM) control with reduced chattering, which able rapidly stabilize the second-order plant high precision. To this end, novel manifold, coined as practical TSM (PTSM) one, first constructed. Once proposed sliding surface reached, Lipschitz-continuous but slope-steep generalized velocity will be established at origin such that global nonsingularity of equivalent ensured. The fast dynamic...
Three different types of entropy weight methods (EWMs), i.e., EWM-A, EWM-B, and EWM-C, have been used by previous studies for integrating prediction models. These three use very ideas on determining the weights individual models integration. To evaluate performances these EWMs, this study applied them to developing integrated short-term traffic flow signalized intersections. At first, two models, a k-nearest neighbors (KNN)-algorithm-based model neural-network-based (Elman), were developed...
This article presents a 6-DOF attitude-orbit synchronous control problem for the space circumnavigation (SCN) mission with parameter uncertainties, time-varying and input constraints. In particular, from perspective of engineering application, measurement uncertainties are taken into account attitude–orbit coupling kinematics dynamics, analytical solution desired attitude is derived based on measured relative orbit information uncertainties. To drive active spacecraft approach to faulty...
Drug-resistant bacteria are a serious threat to global public health. Gram-positive bacterial endolysin preparations have been successfully used fight as novel antimicrobial replacement strategy. However, Gram-negative phage endolysins cannot be applied directly destroy strains due the externally inaccessible peptidoglycan layer of cell wall; this has seriously hampered development endolysin-like antibiotics against bacteria. In study, 3-12 hydrophobic amino acids were successively added...

The model manipulator is established by using Lagrangian mechanism for description its on digital computer, and dynamic response with large sampling interval approximate to Runge-Kutta solutions response, better than that direct Euler-forward difference. discretetime logarithmic sliding mode parameter criteria, which developed refer model, stable surface guaranteed...
This article concerns the guaranteed trajectory estimation problem for unmanned surface vehicles (USVs) via set-membership technique. Taking both rigid-body and hydrostatics kinetics into consideration, nonlinear dynamic model of USV system is derived, where parameters are all unknown. Considering external disturbance nonlinearities, an offline data-based algorithm unknown proposed to obtain set representation parameters, which contain actual USV. Then, based on obtained parameter sets,...

A reset mechanism synthesized into system enhance transient response. motion on...
This paper presents a novel fractional order sliding mode control strategy for quadrotor unmanned aerial vehicle attitude and altitude stabilization. A saturated dynamic model is first obtained via Euler-Lagrange mechanics coordinate translation. By introducing calculus, the newly presented law can achieve fast convergence speed. In addition, with help of bounded functions, our controller deal input limitation caused by characteristics motors propellers. Finally, simulations are carried out...

Based on model mission, a quadratic tracking strategy is designed to track desired position synchronously. Then applied simulation results characteristics seriously affect control quality relative position, which means not suitable for situations require synchronous...
