Chaos is a kind of quasi-stochastic behaviors of determinate nonlinear system. Chaos in three typical topology power electronic converters with a close loop controller is studied in this paper. Recently, how to apply chaos has become the researching focus, chaos control is the basic problem of the application of chaos. To deal with this problem, some existing methods are reviewed and their features are analyzed, and then, this paper places emphasis on chaos control. Diversity chaotic systems are, diversity control methods are.

Nowadays, every country focuses on the smart grid because of the energy deficit. The decrease of the traditional energy caused a lot of problems. The only way to solve them is to find some new fashion energy to fulfill the consumption. So the only thing which can take the place of fossil fuel is renewable energy. There are three kinds of renewable energy which are hot in researching: wind power, photovoltaic power, and tidal power. But all of them are intermittent energy, if we settle the voltage, the power outputs would be hard to forecast and control. This caused a lot of problem for example: the quality of the power and harmonic problems. So we have to find a way to put the intermittent power into order so that it will no longer do harm to the main electric grid.

FPSO(Floating Production Shortage and Offloading) production process fault detection method based on a combination of kernel functions with multivariate statistical is introduced. Kernel function mapping the nonlinear problem is converted into a high-dimensional linear feature space analysis and mapping data in high-dimensional space to extract the nonlinear characteristics to identify the fault. The experimental results show that the kernel function combined with multivariate statistical methods for the FPSO production process fault detection are very effective.

This paper thoroughly analysis the principles and structures of active disturbance rejection control (ADRC), and applied it to shunt hybrid active power filter (SHAPF). Based on the principles of ADRC, this paper regards the uncertainties both within and external of the system model as unknown interference of system, then estimating through extended state observer (ESO), and compensating by nonlinear feedback control (NLSEF), which makes the control law of the system is only related to specified input / output, and reduces detections in control process, i.e. simplifies complex control process. Excellent results can be achieved in system simulation by selecting Parameter, which proves the possibility of control strategy.
