The operation reliability of substation DC system greatly influences the operation safety of the whole system. The site data indicates that defects and accidents occur frequently in DC system and often become the hidden troubles of severer accidents of the power system. Therefore, the effective fault emergency strategy for substation DC system is particularly important. Based on the analysis of the composition and typical defects of the DC system, this paper discuses the fault emergency strategy for substation DC system from the following aspects: fault emergency power supply, fault emergency management organization flow and technical supports provided by intelligent inspection methods. These solutions are effective for the purpose of improving the safety operation level of substation DC system and avoiding the enlargement of fault due to the defects of the DC power supply equipments.

As the uncertainty of information and the decision makers' psychological behavior becomes to be widely concerned in decision making process, a novel method, i.e., evidential prospect theory framework, is proposed based on Dempster-Shafer theory (D-S theory) and prospect theory to address multiple criteria decision making with uncertainty of information under hesitant fuzzy environment. First, belief structure derived from D-S theory is used to model the uncertainty involving expert's subjective assessment. Then a weighted average method to combine belief structures is used to obtain the final aggregated weighting factor for each alternative. Moreover, the expected prospect value of each alternative is obtained by combining the final aggregated weighting factor for each alternative with value function of prospect theory. Based on these expected prospect values, a ranking order of these alternatives can be determined. Finally an illustrative example is given to illustrate the application of the proposed method.

Aiming at reducing the waste of electric energy by traditional electronic load, this paper studies the feed-back single-phase AC electronic load which can effectively reuse the electric energy to achieve the energy reutilization. Based on the “back to back” H-bridge with fully controlled devices, the basic working principle of the whole system is analyzed. The deficiency of traditional PI control algorithm and the advantage of quasi-PR algorithm are studied. In the MATLAB simulation, the PR control algorithm on the control effect is verified and analyzed. The PI and the quasi-PR control algorithm are combined and applied in this paper. The simulation and experimental results verify the feasibility of the control strategy.

Narrowband active noise control (ANC, NANC) systems provide excellent performance in suppressing the annoying noise signals generated by rotating machines, which may be modeled as sinusoidal signals in additive noise. In realworld applications, two important issues including secondary path modeling (SPM) and frequency mismatch (FM), namely, the error of the nonacoustic timing signal sensor, need to be addressed by the NANC system in order to achieve sufficient noise reduction. In this paper, a new robust NANC system is proposed which contains three subsystems, namely: 1) an online secondary-path modeling subsystem designed to track the time-varying secondary path, 2) an FM compensation subsystem providing modified frequencies to every ANC channel, and 3) a cost reduction subsystem where only two x-filtering blocks are placed regardless of the number of the targeted frequencies. The three subsystems are seamlessly integrated such that the entire NANC system enjoys great advantages in both noise reduction and computational efficiency. Simulation results as well as application to real noise are conducted to demonstrate the effectiveness and capabilities as well as robustness of our proposed system.

In this paper, a novel disturbance observer (DOB) design method for time delay systems is proposed to compensate system uncertainties and unknown disturbances in nano manipulating systems. A Modified Disturbance Observer (MDOB) structure for time delay systems is utilized, where the design of low pass filter (LPF) in MDOB is formulated to a mixed sensitivity optimization of infinite dimensional systems. This problem is then solved by Skew-Toeplitz based approach. Furthermore, the constraint conditions of LPF can be realized by the selection of weighting functions. Finally, experimental validation of the proposed DOB design method is performed on a piezo-actuated nano-positioning stage, where the experimental results demonstrate the effectiveness of the proposed approach.
