This article proposes a variable-gain state observer-based sliding mode self-healing control (VSO-based SMSHC) method for wastewater treatment process (WWTP) with changeable external disturbances and sensor failures. To reconstruct the unmeasured system states, novel VSO is developed, in which gains are adjusted by following an automatic mechanism adapting to variation of disturbances. An adaptive compensation coefficient failure factor designed counteract effects on observation tracking...
Demineralized bone matrix (DBM) has been widely used as an allogeneic alternative to autologous graft for repair. However, more extensive use of DBM is limited due its particulate nature after demineralization and rapid particle dispersion following irrigation, resulting in unpredictable osteoinductivity. Here, a new design injectable hydrogel carriers that combine self-healing ability osteogenic properties based on the self-assembly guanidinylated hyaluronic acid silica-rich nanoclays...
Wind generation forecast approaches are typically based on fixed model structures, which might fit well with existing data but fall short in forecasting out-of-sample data. The reason lies that predetermined models cannot always capture the actual dynamic features of wind farms, resulting unavoidable errors. In this paper, a novel ultra-short-term approach multivariate empirical modeling is proposed. time series and explanatory variables applied for attractor reconstruction according to...
Accurate and reliable estimation of generator's dynamic state vectors in real time are critical to the monitoring control power systems. A robust Cubature Kalman Filter (RCKF) based approach is proposed for (DSE) generators under cyber attacks this paper. First, two types attacks, namely false data injection denial service modelled thereby introduced into DSE a generator by mixing attack with measurement data; Second, different degrees sophistication, RCKF algorithm (CKF) adopted DSE, then...
Efficient heat dissipation remains a critical challenge in the research and development of automotive permanent magnet synchronous motors. In this study, Tesla valve cooling channel is innovatively designed, corresponding flow model established using computational fluid dynamics (CFD) simulations. The effects spacing between adjacent valves, number stages, inlet velocities on motor temperature rise pressure drop within are analyzed under varying directions. A comprehensive evaluation 25...
Dear Editor, This letter is concerned with the data-driven fault compensation tracking control for a coupled wastewater treatment process (WWTP) subject to sensor faults. Invariant set theory introduced eliminate completely bounded and differentiable conditions of non-affine dynamics explicitly express inputs. An adaptive mechanism constructed accommodate effects By employing cubic absolute-value Lyapunov criteria, it shown that all signals are error converges an adjustable neighborhood near...
In this paper, the diagnosis method based on wavelet and neural network is proposed. This needs not to collect a large number of data, but simplifies diagnostic process while ensuring accuracy result. The three-phase stator current data were decomposed by db6 function. It does require introduction additional detection equipment, also avoid intrusion that may destruct motor. study has significance in engineering application development on-line system. research fault system will promote...
Doubly fed induction generator (DFIG) based wind turbines have been found to be very sensitive asymmetrical grid fault, wherein the harmful oscillations in electromagnetic torque has being made a big concern. What makes things harder is that latest codes require grid-connected possess ability of positive- and negative-sequence reactive current supporting. Hence, it becomes guide mechanism meet ensure operation safety turbines. Even though tradeoff could between them, still quite difficult...
The doubly fed induction generator (DFIG) based wind turbines are required to output positive- and negative-sequence reactive currents during asymmetric grid conditions by the latest codes. However, electromagnetic stress, related current settings of both rotor- grid-side converters (RSC GSC) DFIG, will be aggravated. That is oscillations in torque DC-link voltage would boosted up. To tackle such problem, need carefully distributed, so as suppress while fulfilling code requirements. do so,...
Recently, the stability issue caused by interactions between doubly-fed induction generator (DFIG)-based wind turbines (WTs) and weak grids has attracted great concerns. Considering complexity of grid-connected system, an effective intuitionistic criterion is quite essential. This paper proposes a Gershgorin-circle based low-complexity generalized Nyquist (LC-GNSC) for DFIG-based WTs. Firstly, system criterion, named LC-GNSC, put forward analyzing distance relationship center prohibited...
