This paper presents an inertial-sensor-based portable instrument and its associated swing motion detection algorithm to detect the following several major stages of a full golf swing motion: address, back swing, top of swing, down swing, impact, follow through, and finish. The portable instrument consisting of a microcontroller, a triaxial accelerometer, a triaxial gyroscope, and a Bluetooth wireless transmission module can be mounted on the golf club to measure swing motion signals. A swing motion detection algorithm composed of the procedures of signal collection, signal preprocessing, and swing motion segmentation has been developed for recognizing golf swing motion stages. Experimental results show that the portable instrument with its swing motion detection algorithm is a promising tool for serving as a training assistant tool for golfers.

In this paper, a method to implement the input shaping control in Mechatrolink-III motion system is introduced. Firstly, the underdamped system is theoretically built by modeling. Then, the motion controller of Mechatrolink-III network is designed to apply the input shaper for reducing residual vibration in manufacturing machine. Later, the experimental beam is set-up to verify the effective performance of input shaping technique. The validity of the control strategy is practically performed by testing ZV, ZVD and ZVDD input shapers. Especially, the successful implementation provides an opportunity to apply the input shaper for multi-axes since Mechatrolink-III motion controller supports up to 32 axes. © 2015 Institute of control, Robotics and Systems - ICROS.

This paper is concerned with the design of linear matrix inequalities (LMIs) based optimal state-feedback controller design for seismically excited asymmetric structures (AS) having stiffness irregularities. The system is modelled in terms of mass, natural frequencies, damping ratio and eccentricities to easily obtain torsionally flexible (TF) model. A one storey, two-way asymmetric structural system is used to illustrate the effectiveness of the approach through simulations. The modelled system has bi-lateral and rotational degrees of freedom. Frequency responses show the effectiveness of proposed controller by means of a decrease in the peak values of translation at each resonance frequency. Moreover, the time domain simulation results, acquired by using real time-history data of San Francisco and El Centro Earthquakes also show that proposed controller is very effective in reducing vibration amplitudes of each direction by applicable control signals and guaranteeing the stability of the closed loop system. © 2015 IEEE.

Rolling element bearings constitute the key parts on rotating machinery and their fault diagnosis are of great importance. In this paper, a novel Two-Step fault diagnosis framework is proposed to diagnose the status of rolling element bearings with imbalanced data. The Wavelet Packet Transform (WPT) is used to determine the feature vectors. 16-dimensional wavelet packet node energies were extracted from the original datasets as the feature vectors prepared to input to the classifiers. Next, our proposed framework consists of two steps for the fault diagnosis, where Step One makes use of Weighted Extreme Learning Machine (weighted ELM) in an effort to classify the normal or abnormal categories, and Step Two further diagnoses the underlying anomaly in details. The effectiveness of our proposed approach is testified on the raw data collected from the rolling element bearing experiments conducted in our Institute, and the empirical results showed that our approach is really fast and can achieve the diagnosis accuracies more than 95%.

Compensation control of Dissolved Oxygen in an Activated Sludge System via Hybrid Neuro Fuzzy Technique

Effective treatment of wastewater relies on a dissolved oxygen (DO) concentration level. Insufficient supply of the DO worsen the quality of the effluent (treated water) whereas too much high dissolved oxygen level maximizes energy consumption and cost. Therefore, DO control is highly crucial for economic, performance improvement as well as safety reasons. However, nonlinearities, influent fluctuations together with the time varying parameters of the system make DO control very difficult using classical control techniques. This paper presents compensation control of dissolved oxygen in the system based on hybrid neuro fuzzy technique. The performance of the proposed control algorithm is demonstrated by set-point tracking. For comparison a PID controller tuned using Zeigler-Nicholas method was used. The simulation results indicate that the proposed strategy is quite effective by tracking well the DO set-point trajectories. This kind of control strategy can be applied to real wastewater treatment system. © 2015 The Authors

The methods of cooking oil discerning are important for the sustainability of the cooking oils supply chain. Classical methods to measure cooking oil quality based on gas chromatography (GC) and high-performance liquid chromatography (HPLC) are too expensive for widespread industrial or household uses and require samples to be analysed in dedicated laboratories thus incurring significant time penalty. Therefore, efforts to develop a reliable and highly sensitive system that may provide on-site cooking oil discrimination is an important priority. Presented research work describes a real time non-invasive discriminating technique for cooking oils. A planar electromagnetic sensor consists of the combination of two sensors which are a meander sensor and an interdigital sensor. The meander type of coil is connected in series with the interdigital coil. Due to the ac voltage applied, the combination of meander and interdigital coils produce electromagnetic field which interacts with the material under test. Three types of cooking oil were prepared namely corn oil, refined palm oil, and sunflower oil. The impedance spectra so obtained showed that the sensor was able to detect the difference between different types of cooking oil samples. Both theory formulation and experiment outcomes were used to testify the measurement for cooking oil discrimination. © 2015 IEEE.

In this paper, to study the load characteristics of the asymmetric bilateral linear switched reluctance generator, theoretical analysis is first derived. Then the characteristics of the machine are investigated by the finite element method. Experiments at different loads are carried out for the asymmetric bilateral linear switched reluctance generator. The experiments are based on dSPACE DS1104 controller board and control Desk software package combined with Matlab/Simulink toolbox. The results demonstrate that each phase is decoupled from the magnetic circuit, and with the increment of load, the rate of discharging current increases. © 2015 IEEE.

In this paper, a nonlinear adaptive control of a 3D overhead crane is investigated. A dynamic model of the overhead crane is developed, where the crane system is assumed as a lumped mass model. Under the mutual effects of the sway motions of the payload and the hoisting motion, the nonlinear behavior of the crane system is considered. A nonlinear control model-based scheme is designed to achieve the three objectives: (i) drive the crane system to the desired positions, (ii) suppresses the vibrations of the payload, and (iii) velocity tracking of hoisting motion. The nonlinear control scheme employs adaptation laws that estimate unknown system parameters, friction forces and the mass of the payload. The estimated values are used to compute control forces applied to the trolley of the crane. The asymptotic stability of the crane system is investigated by using the Lyapunov method. The effectiveness of the proposed control scheme is verified by numerical simulation results. © 2015 Institute of control, Robotics and Systems - ICROS.
