To deal with pattern synthesis of antenna arrays, a chaotic particle swarm optimization (CPSO) is presented to avoid the premature convergence.By fusing ergodic and stochastic chaos, novel algorithm explores global optimum comprehensive learning strategy.The searching region can be adjusted adaptively.To evaluate performance CPSO, several representative benchmark functions are minimized using various algorithms.Numerical results demonstrate that proposed approach improves significantly, in...
In order to enhance the overall power generation efficiency of cascade hydropower, it is essential conduct modelling optimization its in-plant operation. However, existing studies have devoted minimal attention detailed turbine operating performance curves within economic operation model. This represents a significant challenge practical application results. study presents refined model hydraulic curve, which was established by combining particle swarm (PSO) algorithm and backpropagation...
Parameter estimation is an important part in the modeling of a hydro-turbine regulation system (HTRS), and results determine final accuracy model. A normally non-minimum phase with strong nonlinearity time-varying parameters. For parameter such nonlinear system, heuristic algorithms are more advantageous than traditional mathematical methods. However, most heuristics based their improved versions not adaptive, which means that appropriate parameters algorithm need to be manually found keep...

Abstract Fault diagnosis is an effective tool to ensure safe operation of machinery and avoid serious accidents. As most currently used fault methods usually employ mapping relationship established by training samples their labels achieve classification testing samples, it difficult for them under the condition incomplete sample types. In addition, previous studies focus on feature extraction single-channel vibration signal, which cannot get complete information. To solve above problems, a...
De-noising of signal processing is crucial for fault diagnosis in order to successfully conduct feature extraction and an efficient method accurate determination cause. In this paper, the empirical mode decomposition (EMD) thresholding-based de-noising probabilistic neural network (PNN) are respectively used vibration rotor compared with wavelet technology back propagation (BPNN). The results show that clear iterative EMD interval thresholding performs better than signal, avoids basis level....
