Unmanned underwater vehicle (UUV) has been applied for civil field all over the world. In technologies of UUV, the underwater recovery technology plays an essential part. And the superior precision control system is necessary for UUV underwater recovery. In this paper, the research background is the mother ship carries UUV recycling in piggyback method. And the important point is the method of dynamic...
Proportional, integral and derivative (PID) controller has been widely used in many aspects of the industries since its theory was published. In this paper, a systematic approach for the tuning strategy of MacPID controller parameters for first order plus dead time (FOPDT) model is proposed. This method aims to simplify the process PID parameters adjustment and to achieve a desired effect in the same...
In this paper, a new learning method tolerant to imprecision is introduced to fuzzy tree (FT) modeling method. The learning method is called ε-insensitive learning or ε learning, where, in order to fit the FT model to real data, the ε-insensitive loss function is used. FT method adaptively partitions the input space and is irrelevant to the dimension of the input space. For the consequent parameters,...
This paper discusses the capacitated hub and spoke airline network design problem. Against the uncertainty of cost and traffic, a mathematical model is established using robust optimization method. In view of the characteristic of robust solution as well as the question complexity, an ant colony algorithm with human study behavior (HACA) was put forward. Finally, the algorithm is tested by an example.
