A needle-type dispenser, consists of a thin needle and a glass capillary, has been developed for micro-droplet application from high viscosity liquids. A gap, which is a distance between the needle tip and the target surface, is formed in micro-droplet. If the gap is fluctuated, volumes of applied micro droplets are unstable. Therefore, a contact-detection method of the needle-tip droplet and the target surface is proposed. The needle is vibrated by the piezoelectric element through the leaf spring in the proposed method. Contact of the needle-tip droplet and the target surface can be detected from needle-vibration characteristics. In this paper, control of the gap and droplet volume using needle-vibration characteristics is reported.

Aiming at a lack of systematic investigation on magnetostrictive force sensor using giant magnetostrictive materials (GMM) as the sensitive element, a giant magnetostrictive force sensor which uses a GMM rod as the core element is proposed in the paper. The force sensor can measure static and dynamic force simultaneously. The systematic design process and method are expounded in detail. Among them, the magnetic circuit is designed and analyzed by finite element method. Based on these, working conditions and component parameters of the sensor are analyzed through theoretical analysis and experimental measurement. At last, the static and dynamic output characteristics under the optimal working condition are studied by experimental method. The design method and analysis results lay a foundation for the development of giant magnetostrictive force sensor with GMM.

Failure of an actuator in the multi-actuated control surfaces causes catastrophic structural failure due to oblique deflection. In this paper, a networked fault tolerant control strategy to accommodate actuator failure with an application to a modern aircraft is presented. The proposed control strategy is based on intelligent subsystems, such as smart actuators, that are interconnected through a bi-directional digital communication network. A smart actuator is capable of providing information on the device health status that can be used to tolerate faults. This information is then used not only to prevent undesirable force acting on the control surface by driving normal actuators, but also to tolerate the faulty surface by re-allocating redundant surfaces. Simulation results with an aircraft show that the proposed fault-tolerant control method can effectively maintain the desirable control performance in the presence of failure with an actuator in the control surface.

Shaft vibration of large steam turbine has a characteristic of sub-Gaussian signal with predominant components of rotating speed and its harmonics. Most of faults occurred on shaft indicate the change of harmonics with nonlinear coupling reciprocity each other, that makes it difficulty to identify the fault source and extract the fault feature from vibration signals by means of power spectral analysis based on second-order statistical analysis. This paper took an unstable vibration phenomenon with half frequency characteristic of a large steam turbine as an example, and made use of higher order statistics analysis (HOSA) to determine the fault with half frequency characteristics. By comparing the bispectrum and 1(1/2) dimensional spectrum of vibration signals under stable condition with unstable condition, the nonlinear harmonic coupling characteristics of the half frequency component was determined. A method for fault feature extraction was proposed by using the corresponding component in bispectral marginal spectrum and in 1(1/2) dimensional spectrum as feature values to monitor the trend of unstable vibration. And fault recognition and classification were made according to the Fisher criterion. The results show that these feature extraction methods of quadratic phase coupling can clearly reveal the great change caused by abnormal vibration of steam turbine, and reveal the non-Gaussian nonlinear characteristics of vibration signals. The characteristic values are quite sensitive to faults, and they can effectively restrain the Gaussian noise in vibration signals. So they are very suitable for automatic fault diagnosis.

This paper presents an energy-saving, open-loop control technique for a flexible manipulator with point-to-point motion. In the proposed method, the joint angle of the manipulator is expressed by an artificial neural network (ANN). For the ANN, we use a vector evaluated particle swarm optimization (VEPSO) algorithm as the learning algorithm. The maximum residual vibration amplitude and the operating energy are adopted as the multi-objective functions of the VEPSO algorithm. By operating the manipulator along the trajectory obtained by the proposed method, the residual vibrations can be suppressed; thus, saving energy. In other words, the proposed method is an open-loop control that does not require sensors to measure unwanted vibrations. The performance of the proposed control scheme is confirmed by numerical simulations. In addition, the effectiveness of the proposed approach is experimentally verified.

The optimal pyroelectric infrared (PIR) sensor arrays placement similar to optimal multi-camera placement in computer vision (CV), aims to maximize the coverage and spatial resolution and minimize the cost. In this paper, we propose an implementation of a genetic algorithm (GA) based optimization approach for the design of PIR sensing model which is designed empirically in the literature. The optimization process entails the deployment of the sensors and the modulation of sensors' fields of view (FOV). The conventional design need more prior knowledge on the sensing system, while the proposed optimization approach enables the design more flexible and accurate with little prior knowledge. This optimization approach is illustrated by designing a PIR sensing model for human-locating system, and the experimental results testify the validity of the GA-based design approach.

This paper presents a new empirical leakage model of valve. The whole hydraulic system is studied: the system's model utilizing the proposed leakage formula is compared against another model, a known semi-empirical model employing the idea of pseudo section in flowrates. One statistical analysis approach is applied to modeling, using the noise-corrupted physical data. The robustness of models is verified with two new independent situations. Results from fitting and verification have shown that the system model with the proposed leakage formula describes the system dynamics more properly and matches the real responses better.

A vision-based control of SMA-actuated polymer gripper with force sensing is implemented and tested. The gripper system consists of PU (polyurethane) mechanism of gripper with force sensing arm, SMA actuator, and visual-based position and force sensing system. The information of gripper motion is tracked by utilizing computer-vision method through extended Regional Edge Statistics (ERES) algorithm. The position information of gripper tips together with the deflection of force sensing arm is utilized for sensing force. Closed-loop control including PI, PI-FF (PI with feedforward), and FE-PI (fuzzy expert PI) controller are implemented and tested. FE-PI controller is employed for testing the performance of sensing gripping force in grasping of 38μm metal rod.

Automated fish feeding system has been developed to overcome feed waste and water pollution problems. However, typical existing automatic fish feeding system is relatively high cost in maintenance, high energy consumption and has limited pond access area. This paper proposes a novel automated fish feeding system that combines feed dispensing and distribution as one process. A motor driven natural fiber cable is utilized to deliver top hung feeder for feeding process. Such method gives free access around the pond and able to deliver the feeder at any form of fish farm layout. In addition, it has relatively lower structure maintenance cost. The reliability test result showed the feeder positioning accuracy in average was between −1.33mm backward and 1.83mm forward. The accuracy was influenced by the cable tension.
