Backing up control of the truck-trailer system, which is nonlinear and unstable, is a well-known benchmark for examining the nonlinear control design techniques. This paper presents a single-input-rule-modules (SIRMs) connected type-2 fuzzy logic control scheme for this nonlinear multi-variable system. And, to improve the control performance, genetic algorithms (GAs) are adopted for the optimization of the controller parameters. At last, in order to demonstrate the effectiveness and superiority of the proposed control scheme, simulations and comparisons are given. Simulation results show that the designed fuzzy controller can smoothly achieve backing up control of the truck-trailer from all initial positions. Comparisons with type-1 fuzzy controllers demonstrate that the type-2 fuzzy controller with more parameters can provide better performance. © 2012 Chinese Assoc of Automati.

According the radial flutter extension structure problems in commonly used fire alarm system, a novel topology structure of fire alarm systems based-on holographic crystal forms was proposed. It was composed of multiple devices, including intelligent fire detectors, which can communicate with each other, record fire information and judge, alarms, security, evacuation lights etc. Each device can record all of the information so as to form the hologram. These devices on each floor level in buildings and decorated with vertical layout in the staircase, so that fire alarm system topology based-on holographic crystal forms was set up. The systems can ensure the normal operation of other devices in case that central control equipment failed in extreme cases. And then the automatic fire safety equipment continued to automatically control fire rescue and guide the staff in the correct escape route. Moreover, when a device or a line goes wrong, only failure equipment or system was cut off line, and others were still able to keep communications. Compared with other methods, this new system does not affect the normal equipment of the work. © (2012) Trans Tech Publications, Switzerland.

This paper investigates adaptive state feedback stabilization for a class of feedforward nonlinear systems with zero-dynamics, unknown linear growth rate and control coefficient. For design convenience, the state transformation is first introduced and the new system is obtained. Then, the estimation law is constructed for the unknown control coefficient, and the state feedback controller is proposed with a gain updated on-line. By appropriate choice of the estimation law for the control coefficient and the dynamic gain, the states of the closed-loop system are globally bounded, and the state of the original system converges to zero. Finally, a simulation example is given to illustrate the correctness of the theoretical results. © 2015, Institute of Systems Science, Academy of Mathematics and Systems Science, CAS and Springer-Verlag Berlin Heidelberg.

This paper investigates the problem of global stabilization by adaptive state feedback for a class of feedforward nonlinear systems. Different from the existing results, the systems considered have unknown control coefficient with known sign. By introducing the state transformation, the new system is obtained which is convenient for control design. Then, the estimation law for the control coefficient is constructed, and the state feedback controller is proposed with the gain updated on-line. It is shown that the global asymptotic stability of the original system can be guaranteed by appropriate choice of the dynamic gain and the estimation law for the control coefficient. Finally, a simulation example is given to illustrate the correctness of the theoretical results. © 2012 Chinese Assoc of Automati.

To realize the remote control and parameter monitoring of different electrical equipments, such as air conditioning equipments, lights and water pumps, etc., an Internet of Things for building electrical equipments is constructed and its network topology and functional structure are explored in this paper. In this Internet of Things, there exist three main functional blocks - the wireless measurement and control block, the room controller and the environment block. The issues on the self-organization and protocol of the wireless sensor network, which is used for information exchange in these functional blocks, are also studied. What is more, an equipment-management system, which can communicate with the room controllers via Ethernet, is provided on the management computer to realize the remote control of building electrical equipments. At last, an example is given to show how the electrical equipments can be connected to the Internet of Things and be controlled remotely. © 2011 Springer-Verlag.

X-ray Digital imaging is an innovative method of metal fusion welding quality evaluation. To improve the accuracy, the digital imaging sensitivity must be increased by studying the optimal radioactive parameters. At first, the basic elements, inherent characteristics and imaging principle have been analysed systematically. Secondly, the optimization method of sampling rate, stacking frames, focal length, cube voltage and current have been studied based on the phisical characteristic of FPD(Flat Panel Detector). At last, the method has been verified upon two platforms. The experimental results from different systems proved correctness and applicability. © (2014) Trans Tech Publications, Switzerland.

This paper investigates the problem of adaptive disturbance attenuation by output feedback for a class of nonlinear systems with unmeasured states dependent growth. Different from the existing references, the systems studied have more unknown parameters, especially uncertain control coefficients. To solve this problem, the dynamic high-gain K-filters are introduced, and a state observer is constructed based on the K-filters. In output feedback controller design process, to-be-determined design parameters are introduced, to add the design freedom. It is shown that the global stability of the closed-loop system can be guaranteed by the appropriate choice of the dynamic gain of the K-filters and the design parameters, and hence disturbance attenuation is achieved in the sense of L 2-gain.

The Internet of Things for Building Electrical Equipments (IOTBEE), which introduces the Internet of Things (IOT) technology to manage and control all kinds of building electrical equipments, establishes an efficient way for energy-saving in intelligent buildings. However, most of the electrical equipments do not have controllers suitable for communication with the IOTBEE. To realize the control of the building electrical equipments in the IOTBEE, controllers for such equipments are designed in this study. Provided with the switching control interface, the infrared control interface and the serial port control interface, the designed controller can be used to control many types of building electrical equipments such as the water dispensers and the air-conditioners in the IOTBEE. Additionally, the wireless network technology and the harmonic detection technology are adopted in the hardware and the software design of the controllers. Besides common functions, the designed controller can be used for detecting power consumption. © 2012 IEEE.
