For an aircraft flying in atmosphere a BP neural network controller based on the active control technology is designed. The design goal is to reject the influence of a rotary gust disturbance to the normal overload of the aircraft. In order to improve the dynamic response of such aircraft, the active control technology which will act on the longitudinal control is proposed. The designed controller...
This paper presents a novel method to search face candidate regions in color images. First, a skin-color model is used to get the skin regions. Then, particle swarm optimization (PSO) is utilized for searching face candidate regions, which can save time and eliminate small noises. Experimental results show that this searching method is super to the conventional method which scans the whole image pixel...
Adaptive noise cancellation technology is a very good signal processing technology, which can eliminate background noise effectively. In order to restrain the traditional adaptive canceller from trapping in local optimum, the improved PSO algorithm is leading into the mutation operator according to standard derivation of swarm fit value to inhibit local optimum, and design an adaptive noise canceller...
Greenhouse environment models easily fitted strong noise data, and its' generalization decreased. In this paper, ROLS (Regularized Orthogonal Least Squares) algorithm effectively decreased the influence of noise data, and automatically designed smaller NN structure. PSO (Particle Swarm Optimization) algorithm optimized the parameters of model. Model was experimented with spring environment data of...
