In this study, quadrotor vertical taking off and landing (VTOL) control problem of a quadrotor is investigated. A control strategy which has an inner-outer loop structure is proposed. A backstepping based controller is designed for the outer loop to fulfill position tracking aim. The inner loop is regarded as a nominal system with lumped disturbances which contains parameter perturbations, external...
The most challenge of dynamic path planning lies in that the high unpredictability of environmental information. With the strong space search ability and learning ability, artificial immune network (AIN) has been used for path planning. Polyclonal artificial immune network (PCAIN) solves the problems of immature convergence and local minima with the increasing diversity of antibodies. In this paper,...
Hydropower station optimal operation is a complex nonlinear combinatorial optimization problem. A novel culture particle swarm optimization algorithm for optimal operation problem in hydropower station is suggested. A local random search operator to achieve knowledge structure in belief space and enhance the population diversity and increase the capacity of global search with the introduction of culture...
How to effectively filter out vulgar network cultural products is something we must address the issue with the increasing of all kinds of bad information on the internet. The rise of evolutionary game theory is a theory combining together with the game theory analysis and dynamic analysis of the evolution process. For the effective implementation of incentive policy to prevent bad information, this...
Multi-robot system can improve the efficiency of mapping and exploration. One of the key problems is when and how to merge the partial maps acquired by robots independently to share environmental information between robots. This paper studies the problem of fusing two partial maps without common reference frames and relative position information of robots. On the basis of the similarity metric, the...
