This paper aims to propose a fallback system isolated from man-in-the-middle attack (MITM) for networked control systems. In this paper, fallback is an incident response of the control system in which facilities are preferentially protected and a minimal system operates during MITM. Since the communication contents of the networked control systems can be tampered with by MITM, the proposed system named a "fallback system" is installed in a control target side, and the fallback system detects MITM without the communication contents. This system detects MITM based on the bilinear observer and switched Lyapunov function. When MITM is detected, normal operation is switched to fallback operation automatically. As a first step of this study, a selector and a fallback unit of the fallback system are developed. A practical experiment simulating a simple defective discriminator is shown.

Electric Power Research Institute State Grid Shandong Electric Power Company Jinan 250003 China.

Collaborative Innovation Center for Global Energy Interconnection (Shandong) Jinan 250061 China.

In this paper, a cooperation method between wind farm and Electric vehicle battery switch station (EVBSS) was proposed. In the pursuit of maximizing their own benefits, the cooperation between wind farm and EVBSS was formulated as a Stackelberg game model by treating them as decision makers in different status. As the leader, wind farm will determine the charging/discharging price to induce the charging and discharging behavior of EVBSS reasonably. Through peak load shifting, wind farm could increase its profits by selling more wind power to the power grid during time interval with a higher purchase price. As the follower, EVBSS will charge or discharge according to the price determined by wind farm. Through optimizing the charging /discharging strategy, EVBSS will try to charge with a lower price and discharge with a higher price in order to increase its profits. Since the possible charging /discharging strategy of EVBSS is known, the wind farm will take the strategy into consideration while deciding the charging /discharging price, and will adjust the price accordingly to increase its profits. The case study proved that the proposed cooperation method and model were feasible and effective.

In this study, a control strategy to improve the fuel economy was proposed for a PHEV(plug-in hybrid electric vehicle) considering driver tendency. To identify the driver tendency, a driver model which reflects the driver tendency was developed using the driving data. The target PHEV model was developed based on MATLAB/Simulink and validation of the vehicle model was performed by experiments. From the driving data, the driver model which can reflect the driver tendency was developed. To describe the driver tendency, degree of driver aggression(DDA) was proposed, which was determined by fuzzy logic. Using the DDA, a PHEV control algorithm was proposed to improve the fuel economy, which consists of the engine on/off and battery charge-engine operation. The engine on/off control reduces frequent engine on/off for a high DDA(wild driver), whereas the battery charge-engine operation controls the engine operation by considering both the engine thermal efficiency and powertrain efficiency to maintain the battery SOC. It is expected that proposed control algorithm provides improved fuel economy of the target PHEV.

Fan plays an irreplaceable role in the ventilation of underground environment. It will cause serious consequences once the fan fails. So it is essential to do fault diagnosis of fan to prevent the emergence of break down. Spectral analysis method is a simple and effective method for signal analysis and it has been widely used in fault diagnosis of rotating machinery. This paper has researched the bearing fault of fan on the base of in-depth study of the frequency characteristics of typical faults fan. High-frequency noise of vibration signal has been removed through wavelet soft thresholding method. Get its spectrum characteristic of the reconstructed signal, and then the failure category of signal is discriminated by comparing its characteristic frequency to typical faults frequency in theory. Combining the advantage of LabVIEW and MATLAB, we implement the algorithm through two of them, accomplishing denoising and spectral analysis of vibration signals, completing fault diagnosis of fan. © 2015 Technical Committee on control Theory, Chinese Association of Automation.

SCADA (Supervisory control And Data Acquisition) system is a basic infrastructure of modern power systems. SCADA data are widely used in applications such as state estimation, power flow calculation, and on-line security assessment. The accuracy of the SCADA data directly affects the implementation of power system automatic control. In practice, the error of the SCADA data may deviate from its factory precision due to the influence of the equipment aging, data transmission and so on. To quantitatively evaluate the validity of the SCADA data, a consistency index is defined in this paper. Some SCADA data from several substations of a power gird is checked with the consistency index to reveal its reliability.

As a key element in the semiconductor industry, efficient and stable transfer of the wafer set the very high re- quest to the wafer transfer manipulator. At present, wafer transfer robot(SCARA-type, R-θ type) widely used in IC manufacturing equipment can only realize translational transmission to wafer, can not realize the posture change. So wafer transfer acceleration can only rely on its own gravity to generate frictional force to achieve, translational transmission greatly limits the transmission efficiency of wafer. In response to this shortage, this paper, starting from analyzing the adhesion mechanism of microstructure array, analyzes the wafer transfer acceleration performance. The result shows that: the maximum acceleration using the way of pose adjustment transfer wafer is up to 7.6m/s2, much larger than the acceleration by the way of horizontal pose transmission. © Shen et al.

This paper proposed the FSVM (Fuzzy Support Vector Machine) based on affinity to achieve the intelligent wheelchair motion control. The gravity center, which can be computed by calculating the weights of four force sensors under the wheelchair seat, is the key factor to determine the intention of movement of the user. The improved fuzzy membership function of FSVM can reduce the effect of clustering gravity center caused by abnormal clustering gravity center data generated from malfunction. Comparing with the traditional SVM (Support Vector Machine), the improved FSVM algorithm has lower error rate. This paper further validates the practical feasibility and validity of the proposed control algorithm. The experiment results show that the proposed algorithm can improve the precision of omnidirectional intelligent wheelchair motion control.
