This paper introduces present state of our novel attempt to apply organic field-effect transistors (OFETs) to large-area flexible terahertz-wave (THz-wave) sensors utilizing small band-edge fluctuation in organic semiconductors. We found that small random potential fluctuation always appears at the highest-occupied-molecular-orbital (HOMO) band edge of pentacene thin films and its amplitude is insensitive to the growth conditions of the pentacene layer and the composition of the substrate. The height of potential barriers in the fluctuated band is within the range of 1-10 meV, which corresponds to the THz photon energy. According to the modulation-absorption spectroscopy with OFET structure, holes in pentacene exhibited sufficiently large absorption cross-section in THz range. The Drude-Lorentz model cannot explain the shape of absorption spectra of the holes accumulated in pentacene. THz-wave electric-field distribution in OFETs was also calculated using the finite-difference time-domain (FDTD) method to obtain the dependence of sensitivity on frequency and polarization direction.

This paper presents summarized electromagnetic and thermal design of interior permanent magnet motor for a low-floor tram TMK 2200. Motor geometry is optimized for maximum torque density using differential evolution algorithm. The influences of winding configuration on power losses and thermal transients in the motor during one driving cycle of the tram have been analyzed. The results indicate that an optimal number of turns per slot and parallel paths can be found to yield minimum temperatures in various parts of the motor considering the intermittent character of the load.

In 2008 a physical device that contained a layer of titanium dioxide located between platinum electrodes became known as the HP-Memristor. Many models of this device, in different degrees of abstraction, were presented in the literature. This paper describes the simulation of some of these models, written in the object oriented language Modelica, with different numerical algorithms and gives an overview of their efficiency and stability. © 2013 TU Dresden.

Delamination is a major problem in drilling of fiber-reinforced composite materials. Thrust force is an important factor leading to propagation of delamination during drilling process. One of effective methods to reduce machining forces is application of ultrasonic vibrations. In this study ultrasonic assisted drilling is applied to reduce thrust force in drilling of GFRP laminates. In order to conduct experiments a setup is designed and fabricated to apply both vibrations and rotation to drill bits. Using Taguchi method, a set of experiments is conducted with feed rate, spindle speed, and ultrasonic vibration amplitude as control factors. The results show that applying ultrasonic vibration reduces the thrust force and therefore the drilling induced delamination dramatically.

Acid-pickling plates and strips speed control system by microwave heating based on self-adaptive fuzzy PID algorithm

引用

Journal of Central South University 2012年第8期19卷 2179-2186页

作者：杨彪彭金辉郭胜惠张世敏李玮何涛 Faculty of Information Engineering and Automation Kunming University of Science and Technology Key Laboratory of Unconventional Metallurgy of Ministry of Education(Kunming University of Science and Technology) Faculty of Metallurgical and Energy Engineering Kunming University of Science and Technology WISDRI(Wuhan Iron&Steel Design&Research Institute)Engineering&Researching Inc.Ltd.

Double self-adaptive fuzzy PID algorithm-based control strategy was proposed to construct quasi-cascade control system to control the speed of the acid-pickling process of titanium plates and strips. It is very useful in overcoming non-linear dynamic behavior, uncertain and time-varying parameters, un-modeled dynamics, and couples between the automatic turbulence control (ATC) and the automatic acid temperature control (AATC) with varying parameters during the operation process. The quasi-cascade control system of inner and outer loop self-adaptive fuzzy PID controller was built, which could effectively control the pickling speed of plates and strips. The simulated results and real application indicate that the plates and strips acid pickling speed control system has good performances of adaptively tracking the parameter variations and anti-disturbances, which ensures the match of acid pickling temperature and turbulence of flowing with acid pickling speed, improving the surface quality of plates and strips acid pickling, and energy efficiency.

The increasing demands on quality of power, emissions and overall performance of combustion engines lay new goals for the hardware and the software development of control systems. High-performance embedded controllers open the possibilities for application of numerical methods to solve the problems of modeling and control of combustion engines. Algorithms for estimation of state and parameters are essential components of many advanced control, monitoring and signal processing engine applications. A widely applicable estimator is given by the Extended Kalman Filter (EKF) which defines a finite memory recursive algorithm suited for real-time implementation, where only the last measurement is used to update the state estimate, based on the past history being approximately summarized by the a priori estimate of the state and the error covariance matrix estimate. The proposed EKF uses an augmented air-path state-space model to estimate unmeasurable mass flow quantities. The EKF algorithm based on the augmented state-space model considerably reduces the modeling errors compared to the open loop estimator simulation and compared to the EKF without the augmentation which is demonstrated on a standard production Diesel engine data. The experimental validation of the observed state quantities is performed against the measured pressures and turbocharger speed data. The estimated mass flow quantities are indirectly validated through the air compressor flow that is directly validated against air mass flow sensor data. Two two-sensor setups are considered in this study. In the first experiment the intake manifold pressure and the turbocharger speed is used. The second experiment uses the intake manifold pressure and the exhaust manifold pressure as the measurement information for the EKF. The second experiment gives more precise mass flow estimate in term of less bias on the estimates, but more variance due to the high frequency exhaust manifold pressure variations caused by the
