研究系统结构和参数变化时性能变化情况，得到的平均电流控制型 PFC Boost 变换器的混沌分岔
图，为更好地理解和设计这种变换器提供了有利的工具。(The structure of average current controlled power factor correction (PFC) Boost
converter is introduced, and its working principle is analyzed. The PFC Boost converter is simulated
using the model established with Power System toolbox and the C-MEX file S-function model
respectively. Simulation results show that the C-MEX file S-function model can simulate the all state of
the converter including discontinuous conduction mode with high speed. Experimental results show the
correctness of the simulation results and the proposed method. The method is suitable for simulation
the performance changing with the variation of system structure or parameters. The bifurcation diagram
is derived for PFC Boost converter using this method, which is very useful for better understanding and
better design of the converter.)

K-meanCluster
How the K-mean Cluster work
Step 1. Begin with a decision the value of k = number of clusters
Step 2. Put any initial partition that classifies the data into k clusters. You may assign the training samples randomly, or systematically as the following:
Take the first k training sample as single-element clusters
Assign each of the remaining (N-k) training sample to the cluster with the nearest centroid. After each assignment, recomputed the centroid of the gaining cluster.
Step 3 . Take each sample in sequence and compute its distance from the centroid of each of the clusters. If a sample is not currently in the cluster with the closest centroid, switch this sample to that cluster and update the centroid of the cluster gaining the new sample and the cluster losing the sample.
Step 4 . Repeat step 3 until convergence is achieved, that is until a pass through the training sample causes no new assignments. (How the K-mean Cluster workStep 1.
