Partial shading of photovoltaic cells would happen frequently during power generation process. With the result that output power-voltage (PV) characteristic curve of PV arrays could result in multiple power peaks, the traditional technology of maximum power point tracking (MPPT) control algorithms will be failure. Based on this situation, this article mainly proposed a MPPT(maximum power point tracking)...
As a modern Evolutionary Algorithm, Differential Evolution (DE) is usually criticized for its slow convergence when compared to Particle Swarm Optimization (PSO) on the PSO’s benchmark functions. In this paper, by combing the merits of PSO and DE, we first present a new hybrid DE algorithm to accelerate its convergence speed. Then a novel mutation strategy with local and global search operators is...
This paper proposes a new particle swarm optimization (PSO) algorithm with an adaptive weight. Benchmark tests of the algorithm is described. Compared with standard PSO, it shows better convergence as well as ability of escaping from local optima. Diesel engines must meet the increasing demands for higher efficiency, cleaner exhaust gases and better drivability. Model-Based control is one of effective...
