This article proposes a decomposition-based multi-objective differential evolution particle swarm optimization (DMDEPSO) algorithm for the design of tubular permanent magnet linear synchronous motor (TPMLSM) which takes into account multiple conflicting objectives. In process, objectives are evaluated by an artificial neural network response surface (ANNRS), is trained samples TPMSLM whose performances calculated finite element analysis (FEA). DMDEPSO hybridizes (DE) and (PSO) together,...

This paper investigates the problem of connectivity-preserving flocking multiple autonomous agents with second-order dynamics. First, inverse power iteration algorithm is formulated in a completely distributed manner to estimate algebraic connectivity, i.e., second smallest eigenvalue group Laplacian, as well corresponding eigenvector. Furthermore, gradient-based algorithms that exploit decentralized eigenvalue/eigenvector estimation are developed both steer agent desired motion and maintain...

In order to solve the challenging problem of diagnosis for sensor bias and drift faults, a method fault based on least squares support vector machine (LS_SVM) online prediction is proposed. paper, real-time outputs are made full use establish LS_SVM model. Through residual which obtained by comparing model actual output sensor, detection faults can be achieved. Based sequence, on-line identification achieved as well. A established toolbox matlab simulink in this simulation results show that...

Evolutionary search has been widely implemented for the adjustment of controllers' parameters. Nevertheless, structure controllers, which a more important role in control systems, seldom studied. To this end, an evolutionary design method controllers is proposed to optimize both structures and parameters simultaneously article. A controller made up combination some basic components relevant The can be transformed into optimization problem involving (represented by discrete vectors) real...

This paper investigates a leader-following formation control problem with translational and rotational maneuvers for group of missiles in 3D space. Benefit from the displacements defined neighbors' relative coordinate frames distributed law, whole is able to track leader's trajectory movement rotation after desired shape formed. By incorporating command filters into backstepping-based scheme, flight state constraints overload saturations can be satisfied. It shown that proposed algorithm...

In the process of azimuth measuring, output signal a gyro always contains noises caused by drifting and ambient environmental influence. order to reduce recover original signal, conventional digital filtering methods such as IIR FIR could be used. But outputs these filters would distorted or in lack smoothness under some special conditions. Wavelet analysis is suitable this circumstance for its characteristic multi-resolution time frequency localization space. Therefore, wavelet threshold...

In this paper, we discussed the simultaneous intervention problem that arises from human-robot teams. The concerns with case one human operator has to intervene several robots at almost same time and it cannot be handled properly by existing methods. A model predictive control(MPC) based mixed initiative controller was proposed solve embedding an intention into optimization problem. This method is in essence suitable for general MPC controllers. embedded may cause robot deviate its desired...

Recently, 3D Gaussian Splatting has dominated novel-view synthesis with its real-time rendering speed and state-of-the-art quality. However, during the process, use of Jacobian affine approximation projection transformation leads to inevitable errors, resulting in blurriness, artifacts a lack scene consistency final rendered images. To address this issue, we introduce an ellipsoid-based method calculate ellipsoid on image plane, witch is primitive Splatting. As our proposed cannot handle...

Cooperative adaptive cruise control(CACC), as one of the most important technologies intelligent transportation system(ITS), combines control(ACC) with short range communication(DSRC), which can make platooning distance much more smaller and avoid collision efficiently. As we all know, information vehicles receive from platoon, better overall stability keep. However, that will lead to an increase in communication resource consumption cause signal interference surrounding vehicles. Therefore,...

Disturbance widely exists in control system. Active disturbance rejection (ADRC) has been proved to be an efficient way deal with and achieves great success practice. The most important part of ADRC is extended state observer (ESO), which estimates the states system total disturbance. ESO regards internal external as a disturbance, it eliminates control. faster more quickly controller it. This paper focuses on discrete linear (DLESO), presents predictive (DPLESO). Stability performances are...

Fault diagnosis based on the wavelet packet decomposition, one-against-one support vector machine (SVM) and genetic algorithm (GA) is proposed in order to realize real-time sensor fault accurately. The input feature vectors of SVM are produced by decomposition output signal. GA used obtain optimal parameters network model automatically, which can enhance training speed performance. experiments photoelectric encoder show that combination these methods makes own a better recognition rate...
