AC electroosmosis (AC EO) shows many advantages in collecting microparticles, such as low signal voltage, little sample, real-time detection and integrating in microchip easily. An experiment showed that the microparticles in sample would be accumulated on a fixed field on the surface of the microelectrodes caused by the AC electric field. Based on the phenomena, the velocity field of AC EO in microchannel is explored and the process of microparticles accumulated is explained. The location of microparticles accumulated is determined based on the numerical simulation results, at the same time, the rate relation between the accumulated location and the width of microelectrode, which offers the theoretic base for further analyzing and detecting microparticles.

The instantaneous torque control for torque ripple minimization of switched reluctance motor (SRM) by BP neural network is presented. As SRM has a highly nonlinear characteristics, neural network is well suited for its control. After static torque characteristics of SRM having been measured, the torque model and the inverse torque model are developed based on BP neural network of Levenberg-Marquardt algorithm. The torque ripple minimization can be achieved by optimum profiling of the phase current based on instantaneous torque control. An efficient commutation strategy for minimizing torque ripple as well as avoiding power converter voltage saturation over a wide speed range of operation is proposed. Simulation results verify the feasibility of this torque ripple minimization technique.

In order to obtain the large signal stable control strategy of high-order system, Lyapunov direct method is applied to coupled-inductor Sepic converter for the first time. Extended system of differential equation of Sepic converter is proposed in this paper. Based on Lyapunov stability theory, Lyapunov function is constructed successfully and a globally asymptotic stable control law is obtained. The proposed controller is robustness around the operating point, and good performance of transient responses can be achieved at load changes and input voltage variations. Simulation results confirm the effectiveness of the proposed control law.

In this paper, a new approach is proposed that minimizes the total copper and iron losses in variable speed and/or thrust force linear induction motor (LIM) drive. This method is based on a LIM model that considering the end effect and attraction force. For a given speed and load this model allows the establishment of equations to quantify copper and iron losses, and the relationship between stator field and torque currents for minimum total loss can be deduced. Based on these equations, a loss minimization control algorithm, combined with vector control mode to drive the LIM, is proposed. This algorithm allows the electromagnetic losses in a variable speed and thrust force LIM drive to be decreased while keeping a good dynamic response. The simulated results presented show that it is possible to improve the efficiency of LIM drive keeping a good dynamic response.

The IEEE 802.11e network provides different with QoS (quality of service) guarantee for different traffic streams. The enhanced distributed channel access (EDCA) in IEEE 802.11e MAC protocol is proposed to support prioritized QoS on the basis of the distributed coordination function (DCF) in IEEE 802.11. We first build a new Markov chain model for the EDCA. The model takes into account both the idle state that represents that there are no packets to be transmitted and differentiation based on different AIFS-value for different traffic. We can use the signal transfer function of the generalized state transition diagram to derive a probability distribution of the MAC layer service time and analyze the performance of EDCA from a non-saturated channel to a saturated medium by using M/G/1/K queuing model. The proposed model is calculated numerically and validated against simulation results, we observed a good match between the analytical model and simulation which conforms the veracity of proposed model. Simulation and theoretical results show that despite providing prioritized QoS, the EDCA still can not support strict QoS for real-time application like voice and video unless network works in the non-saturation case. On the other hand, it is inevitable that there is unfairness of channel access to prioritized traffic due to EDCA.
IEEE 802.11e网络针对不同的业务流提供了不同的QoS (quality of service)保证。为了在IEEE 802.11分布式协调功能(DCF)的基础上支持优先级QoS，提出了IEEE 802.11e MAC协议中的增强型分布式通道接入(EDCA)。我们首先为EDCA建立了一个新的马尔可夫链模型。该模型既考虑了空闲状态(表示没有数据包要传输)，也考虑了不同流量根据不同aifs值进行区分。我们可以利用广义状态转移图的信号传递函数推导出MAC层服务时间的概率分布，并利用M/G/1/K排队模型分析EDCA从非饱和信道到饱和介质的性能。对所提出的模型进行了数值计算，并与仿真结果进行了对比验证，结果表明解析模型与仿真结果吻合较好，符合所提出模型的准确性。仿真和理论结果表明，尽管EDCA提供了优先级QoS，但除非网络在非饱和情况下工作，否则它仍然不能支持语音和视频等实时应用的严格QoS。另一方面，由于EDCA的存在，不可避免地会导致优先业务的信道接入不公平。

In order to meet the demands of high-acceleration/high-deceleration and high-precision motion control system, the direct-drive linear motor as the prime motion actuator is widely used in modern motion control systems such as machine tools, ranging from mass transportation to factory automation etc. Among these applications, permanent magnet synchronous linear motor (PMSLM) owing to their simple structure, easy of manufacture and simple control are more frequently used. The advantage of using PMSLM is that it can provide high performance motions with reduced mechanical components, but unlike conventional ball-crew drive, the PMSLM system eliminates the mechanical coupling, rotary-to-linear translators, and reduction gears. Therefore, any change or disturbance in the load will be directly reflected back to the motor and control system, which will cause large deterioration in motion control. In this paper, the model of PMSLM is established firstly; Secondly, a fuzzy sliding mode control based on model reference adaptive control (MRAC) for permanent magnet synchronous linear motor (PMSLM) system, which combines the merits of MRAC, the sliding-mode control and the fuzzy inference mechanism, is proposed. In order to reduce the complex identification of MRAC, the sliding mode control (SMC) is employed in the controller design, which makes the response of the PMSLM system can strictly track the reference mode, and is less sensitive to external load disturbance and the system uncertainties. The introduction of fuzzy control effectively minimized the chattering of SMC. At last, the result of simulation using proposed method is illustrated, which illuminate the proposed method has good tracking characteristic and strong robustness for external load disturbance and the system uncertainty.

The combination of ordinary wavelet shrinkage with total variation minimization was successfully applied. In this paper, we apply the technique with respect to ridgelet coefficients. Firstly, a translation-invariant ridgelet transform is proposed. And then, an image denoising algorithm, based on ridgelet shrinkage and total variation minimization, is given. This algorithm preserves the important information of image and reduces the noise by thresholding small ridgelet coefficients. By replacing these thresholded coefficients by values minimizing the total variation, the algorithm reduces the pseudo-Gibbs artifacts. Experiment results show that this algorithm yields significantly superior image quality and higher peak signal to noise ratio (PSNR).

This paper proposes a hybrid adaptive control strategy to control a hybrid electric vehicle (HEV), and two neural-network-based adaptive estimators of torque and speed, which are of both induction motor (IM) and engine, are proposed too. In order to control HEV effectively, the configuration of the hybrid control system combines a fuzzy neural network (FNN) controller and an adaptive compensated controller. The FNN controller is the main controller to track the expected value of the system; and the compensated controller to compensate the uncertainties of the system; the compensated control law is derived using Lyapunov stability theory. The proposed estimator of IM includes two recurrent neural networks (RNN), one is used to estimate rotor flux and speed, the other is used to estimate stator current. The effectiveness of the proposed control strategy is verified by the simulation results.
