The paper first introduces the basic drive system of a kind of hybrid electric vehicle. It demands high power bidirectional flow capability, with wide input voltage range, and output voltage of energy storage devices such as super capacitors or batteries vary with the change in load. Then the selection and design of aforementioned converter is proposed in this paper. The converter which is like a...
In this paper, according to the respective performance of genetic algorithm and neural network, the authors proposed a new method, based on the model of multilayered feed forward neural network (MLFNN), and it is used to simultaneously measure amplitude and phase angle of harmonic, i.e., genetic algorithm and back-propagation neural network (GABPNN). In this algorithm, the new coding scheme of the...
Solar energy is considered to be the world's most promising new energy technologies. How to find the best control strategy to maximize the advantages of photovoltaic system will greatly promote the development of photovoltaic technology. The variable universe fuzzy control is applied to the maximum power point tracking (MPPT) control in this paper. The variable universe fuzzy control is different...
In this paper, analysis and design for a dual-boost single-phase active power factor corrector with one cycle control (OCC) is presented. The dual boost topology combines rectification and power factor correction (PFC) together. Only one of the two power switches is operated respectively during each positive or negative half line cycles. The controller employs the one-cycle-control strategy, which...

This work presents a controller for maximum wind energy capture of wind power system according to the theory of auto disturbance rejection controller (ADRC). The uncertainties in the torque of turbine and friction are both considered as an unknown disturbance to the system. The expending state observer can evaluate the unknown disturbance. With the nonlinear state error feedback control law, the disturbance...
The simplified mathematical model of the permanent magnet linear motor is developed in this paper. By applying Lyapunov's stability theory, the authors propose a model reference adaptive controller. Then the controller is evaluated by simulation. The results show that the MRAS is superior to the conventional PID controller in dynamic performance and steady precision. The MRAS is robust to the parameter...
