This paper is aimed to explore the equivalent circuit models of piezoelectric ceramics with the consideration of energy dissipation. Based on the electrical impedance, the equivalent circuit models of piezoelectric ceramics are investigated under unloaded and loaded conditions. The characteristics and physical meanings of the circuit models are discussed by considering the frequency range of interest. The circuit models and discussions in this paper can provide a good understanding on the electrical behaviors of the piezoelectric ceramics when designing and analyzing the piezo-based systems.

A novel orientation tracking algorithm is introduced. The algorithm can provide 3DOF orientation information of an object in a hemisphere space. It is based on two-dimensional information about the gravity field and the earth magnetic field. Comparing with the traditional algorithm, it reduced the needed information from three dimensions to two dimensions in operation. It is faster and simpler. The algorithm is validated with a system. The results indicate the algorithm can track the orientation of the object well.

In the medical field and in biotechnology, a new type of micropump that can supply micro liquid flow has urgently been demanded. It is our purpose to develop a type of micropump that has the characteristics of flexibility, driven by a low voltage, good response and safety in body. In this paper, we propose a new prototype model of a micropump using SMA (shape memory alloy) coil actuator as the servo actuator. This paper describes the new structure and the motion mechanism of a micropump using SMA actuator and discusses the possibility of the micropump. This micropump consists of two diffusers (inlet) as one-way valve, a pump chamber made of elastic tube, and a casing. The overall size of this micropump prototype is 16mm in diameter and 74mm in length. Characteristic of the micropump is measured. The experimental results indicate that the micropump has the satisfactory responses, and the proposed micropump is able to make a micro flow and is suitable for the use in medical applications and in biotechnology.

A generalized predictive control (GPC) is introduced, which is applied to the temperature control of a batch-dyeing machine. GPC has good robust and performance in control domain compared to tradition PID, but it is more complex than PID, which means that it is uneasy to implement and tune the GPC in some controllers having only limited mathematic computation ability. But for the fact that a wide class of industrial processes including dyeing process can be modelled approximately with few parameters, the GPC control law can be directly related to the process parameters with some simple polynomials functions. With this method, GPC can be implemented and tuned in a straightforward manner as simple as the PID and thus more industrial practices including dyeing process would enjoy the good performance of GPC.

A novelty method of wavelet-based adaptive multiscale principal component analysis (MSPCA) is proposed for process signal acquisition and diagnosis. The wavelet transform is used to decompose the process signals and at the same time analyze the different scales signals based on multiresolution signal analysis, and then the signals are reconstructed in order to denoise and get rid of disturbances. The adaptive PCA algorithm is adopted to monitor and diagnose abnormal situations on the basis of the multiscale wavelet coefficients, analyze the slow and feeble changes of fault signals that can't be acquisition and monitored by conventional PCA. Furthermore, the theoretic framework and practical process of wavelet-based adaptive MSPCA algorithm about online process signals monitoring and diagnosis are also proposed. Experimental simulations and practical application results verify the validity and dependability of the proposed method.

This paper puts forward a new method of detecting consistence of emulsification liquid. This method is based on the mechanism of Verturi meters. The consistence could be deduced from Bernoulli Equation of the liquid. The consistence of emulsification liquid can be adjusted by adjusting the pressure of input water and the level of the oil. Based on this method, the hardware and software of the device is presented in this paper. The structure of the device is simple and the device is suitable for using in underground coal mine.

Some information, which is not the same as the traditional cause of vibration of diesel engine's high-pressure fuel pipe is given by the use of modern detection technology. From the information & theory analysis, the real cause of vibration of high-pressure fuel pipe is found. The cause is elastic deformation of the pipe. High-pressure of fuel in the course of fuel injection makes the pipe's cross section get elastic deformation and then the curvature of pipe get elastic deformation. That is to say, the real cause is Bourdon Effect of pipe. In the view of energy, the relations of the energy between pressure energy of fuel, strain energy & elastic energy of pipe are described. So the vibration of the high-pressure pipe is caused mainly by the Bourdon Effect, and is one of the main causes of fuel injection system fault.
