Neural networks with good nonlinear mapping abilities can be applied to build simulation model of helicopter. But they have some difficulties such as hardness of selecting network structure, slow convergence speed, local minimum, and over-fitting. To avoid above problems, a modeling method for dynamic nonlinear system based on support vector machine was proposed. This method was applied to build simulation...
Neural networks with good nonlinear mapping abilities can be applied to build simulation model of helicopter. But they have some difficulties such as hardness of selecting network structure, slow convergence speed, local minimum, and over-fitting. To avoid above problems, a method for building simulation model of helicopter based on Wavelet Support Vector Machine (WSVM) is proposed. Marr wavelet is...
As a system identification method, neural network can be applied to build the simulation model of a helicopter. But it has some difficulties such as the hardness of selecting network structure, slow convergence speed, local minimum, and generalization ability question. To avoid the question above, the support vector machine (SVM) method is introduced to the field of flight simulation for the first...
