Purpose Early fault detection of bearing plays an increasingly important role in the operation rotating machinery. Based on properties early signal bearing, this paper aims to describe a novel hybrid method bearings. Design/methodology/approach In adaptive variational mode decomposition (AVMD), strategy is proposed select optimal level K decomposition. Then, criterion based envelope entropy applied intrinsic functions (OIMF), which contains most useful information. Afterwards, local tangent...
A comprehensive analysis on the chaos of a high-dimensional wind power system is performed in this study. more complex than most systems. An 11-dimensional proposed by Huang, which has not been analyzed previous studies, investigated. When systems are affected external disturbances including single parameter and periodic disturbance, or its parameters changed, chaotic dynamics ranges obtained. Chaos existence confirmed calculation all state variables' Lyapunov exponents variable sequence...
The hypersonic vehicle has the characteristics of strong coupling, high uncertainty and complex nonlinearity, leading to an unsatisfactory control performance with traditional design method. In this paper, integrated guidance approach is proposed cope problem. A time-varying longitudinal model first formulated, then overall consisting un-modeled dynamic, parameter external disturbance taken into account. novel finite-time extended state observer developed estimate compensate it in real time....
In order to overcome the bad performance and deficiencies of main steam temperature control system, we combine Model Free Adaptive Control (MFAC) algorithm with conventional PID algorithm. This scheme incorporates modeling together form an integrated intelligent mechanism. The MFAC-PID cascade system is able time delays, non-linearity, disturbance variation. Simulation results have demonstrated efficiency proposed method.
Firing accuracy is a critical quantity of interest in the performance analysis electromagnetic railgun (EMRG) exterior ballistics. Since simulation technique always used to simulate complex physical system at low cost, it employed evaluate firing projectile with uncertainty this paper. An ballistics model railgun, including 3-DOF flight mechanical model, relative kinematic and guidance law developed behavior missile target intercept mission. The studied paper compare capability EMRG...
The electric actuator's operating principle is analyzed of control system in this paper, and the experiment platform setup which aim at classic faults actuator, last result recorded. Multi-sensor data fusion theory discussed one fault diagnosis algorithm put forward. recorded input into model based on two-step "neural network D-S evidential theory". showed that creditable, can direct stable operation
In this paper terminal guidance law considering uncertain factors for flight vehicle is investigated. order to improve the accuracy, continuous non-smooth control theory based nonlinear which can make states converge in finite time derived. Then a finite-time convergence extended state observer introduced into system compensating uncertainties it. With aid of numerical simulation, it demonstrates effectiveness approach yield better accuracy presence abrupt disturbance.
In this paper a novel terminal guidance law for hypersonic vehicle is investigated. order to accelerate the convergence rate of line sight angle, adding power integrator technique based nonlinear which can make converge zero in finite time proposed. Then rigorous stability analysis finite-time shown. It demonstrates effectiveness approach by numerical simulation meanwhile have strong robustness presence disturbance.
