This paper shows that servo-type jerk sensor is realized by rebuilding feedback (FB) circuit of commercially available velocity sensor. After the adjustment of internal PID parameter of FB circuit, it was applied to the linear slider for mechanical impedance control. Once it was confirmed that the sensor has fine phase characteristic, the sensor was also installed on the pneumatic stage to improve dullness of positioning by direct jerk FB.

Sensor-to-controller delay in a remote control system possessing wireless devices is considered in this paper. There is a concern that communication delay would increase when wireless communication is used instead of wired one. The purpose of this paper is to design the networked control system against increased communication delay by using a particle filter. It is assumed that there are three types of communication delay. They are based on uniform distribution, normal distribution, and constant. One of them occurs in our simulation. A particle filter is a method for statistically estimating unobservable values from observable ones and model equations. The influence of each communication delay is reduced by using estimated output in simulation.

This paper proposes a DSP-based camera weft-straightening detection system. Two 12k high-speed line scan CCD cameras are used to obtain texture pattern of fabric. The texture morphology of fabric is analyzed by DSP+FPGA control mode to obtain accurate fabric state. In process of weft rectification, the combination of fuzzy algorithm and PID control is used to adjust rectification device to perform weft skew or weft bending rectification. Experimental results show that the detection system can calculate weft skew angle more accurately, weft rectification ability is strong and precision is high. The detection system is suitable for wide variety of fabrics and has a good application prospect.

The fractional Fourier transform is an important tool to signal processing tasks such as image analysis, machine vision and pattern recognition. In this paper, we studied the main properties of the fractional Fourier transform. And applying these properties to digital watermarks, we propose a new digital image watermarking method. The theoretical analysis and experimental results show that the proposed method has strong robustness against a large number of watermark attacks, namely, it can improve security and robustness of the watermarking. Numerical simulations have also been performed to verify the efficiency of the proposed method.

In this paper, a predictor-based event-triggered control strategy for discrete systems with network-induced delays is presented. In order to weaken the effect of delays, a simple predictor is carefully designed. An event-triggered control strategy is utilized to save limited network resources, which is further decreased by changed event-triggered threshold parameter. In order to obtain unknown state variables, a Luenberger observer is employed. The theoretical analysis and the numerical simulation results prove that the proposed method is effective.

Firstly, the filter variables are used transform the model, and the system model is expressed as a linear function of the minimum inertial parameters. Secondly, the control law and the online updating law of the parameters are designed for the open-loop system, and the stability of the designed control system is derived by using the Lyapunov method. Finally, the effectiveness of the proposed method used is verified by simulation.

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.

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.
