This paper develops an improved TOPSIS (Technique for Order Preference by Similarity to an Ideal Solution) based on grey relational analysis and cloud model theory for dealing with the fuzziness and randomness in muti-attribute decision making. Firstly, some concepts of cloud model theory and grey relational analysis were introduced and an improved forward cloud generator was put forward to normalize the decision matrix of TOPSIS, thus the uncertainty of the decision data was embodied and simulated. Then the steps of the improved TOPSIS were described. The calculation method of the numerical characteristics of the cloud model used to normalize the decision matrix was given. The separation to the positive ideal solution and negative ideal solution was calculated by grey relational analysis method which can reflect the trend relationship between the alternative and the ideal solution. The weight of the criteria was calculated on the basis of the exponential scale of analytic hierarchy process. Finally, a numerical example was given to illustrate the practicality and effectiveness of the proposed method. The method can provide more evaluation information by its statistical nature.

The feedback path (FBP) compensation has been a research topic in the field of active noise control (ANC) for decades and a number of offline and online FBP modeling techniques have been proposed in the literature. In this paper, a novel ANC system equipped with an online FBP modeling (FBPM) and neutralization (FBPMN) subsystem is proposed. The new system consists of three adaptive subsystems, namely 1) ANC controller with only two weights for each frequency target, 2) second-order adaptive IIR notch filter, and 3) an FBPMN filter. It yields very promising performance for narrowband noise signals generated by rotating machines such as fans, motors, large-scale strandcutters, etc. An auxiliary white Gaussian noise is injected into the ANC system to implement the FBPMN, which is scaled by a function of the residual noise to reduce its contribution to the residual noise power. Extensive simulations with synthetic/real secondary paths reveal that the proposed ANC scheme ensures excellent noise reduction performance as well as practically attractive computational efficiency.

A flexible arm has light weight in order to improve the work efficiency and reduce costs. Therefore the damping effect decreases, and the flexible arm vibrates easily. On the other hand, smart materials have many advantages as actuators, and researches on smart materials are actively conducted. This paper introduces model of the flexible arm and a Shape memory alloy (SMA) actuator which is one of the smart material, and proposes a vibration control system based on operator theory for the flexible arm using the SMA actuator with hysteresis. In order to verify the effectiveness of the proposed system, simulation results are shown.

A cooling and heating system using Peltier devices has two spaces, one space is kept at a low temperature, and the other space is kept at a high temperature. Peltier devices have nonlinearity, so it is difficult to control the system. In this paper, an operator based control system using a concept of sliding mode is designed. Furthermore, temperature dependence of thermal conductivity is considered. The effectiveness of the designed controller is confirmed by simulation results.

A timeout threshold estimation algorithm is proposed which apply in mimic defense systems to reduce the waiting time when timeout is happened. It is inspired by the fact that there is a linear relationship in task execution time of a set of heterogeneous executors in mimic defense systems. Experiment results show that our algorithm can generate a specific timeout threshold for each task with high computational efficiency and is particularly suitable for the scene in which the number of arriving tasks changes drastically.

This paper proposes a photovoltaic module integrated microinverter using a gradationally controlled voltage source and a series connected active filter. Recently, a microinverter based on an isolated resonant DC-DC converter is widely used. A typical microinveter can achieve high efficiency around 97%. In addition, a microinverter system can achieve high Maximum Power Point Tracking (MPPT) efficiency by its small photovoltaic area. The proposed circuit is a combination of a gradationally controlled voltage source, an active filter connected in series and an unfolding circuit. This circuit reduces the power to be converted to 1/8 as compared with a conventional inverter. The control strategy for the proposed circuit is also discussed in this paper. Finally, the grid connected operation is verified by circuit simulation.
