In terms of the difficulty of vehicle tracking in complex environment of the visual surveillance system, an object tracking algorithm is proposed for the applications in practical visual surveillance systems for intelligent traffic. A block-based Gaussian mixture background modeling method for object detection is presented to reduce the computational complexity of moving vehicle object abstraction. An adaptive tracking algorithm fused with color features and texture features is described to better adapt the traffic scene variation. The experimental results show that the proposed algorithm can effectively deal with the complex urban traffic conditions and the tracking performance is better than the conventional particle filter method and single feature based non-adaptive object tracking method.

In this paper, a control mechanism is presented to improve the compliance performance of the robot manipulator when it is in contact with the unknown environment. This mechanism guarantees that the dynamics of the whole system follows a target impedance model so that the desired compliance performance is obtained. In particular, under the assumption that the dynamics is periodic, a learning law is developed to estimate the unknown dynamics parameters. Besides, the proposed systematic learning control does not require the accurate force measurement. Its performance and robustness are discussed in details by the rigorous analysis. At last, the validity of the proposed method is verified by simulation. © 2010 IEEE.

This paper studied the calibration method for a type of embedded smart sensors which are integrated with inertial, magnetic and vision sensors. A set of calibration and modeling methods which are suitable for the low cost applications have been proposed. For the deterministic items and nondeterministic items, we used the method of modulus matching of the input vectors and the method of time series analysis to calibrate and modeling them respectively;for the relative rotation between the accelerometers' frame and the camera frame, we proposed a calibrating method which is based on the gravity vector and plumb line. The experimental and simulation results demonstrated the practicability and effectiveness of these methods.

This paper proposed an embedded smart sensor which is consisted of a 6 DOF (Degree Of Free) IMU (Inertial Measurement Unit), a 3-axis magnetic compass, a monocular camera and a DSP processor which is high performance and power saved, and briefly discussed the design and construction of the system's hardware. By using this embedded smart sensor, we proposed a attitude determination method which is based on the quaternion and the epipolar geometry. The experimental results demonstrated the effectiveness of the methods.

Embedded systems have stepped deeper into Integrated Avionics systems, and security is becoming an important concern. Most embedded systems present a number of software vulnerabilities, such as buffer overflows. Furthermore, the rapid growth and pervasive use of embedded systems makes it easier for a sophisticated attacker to gain physical access to launch physical attacks on insecure off-chip main memory. This paper presents a novel compiler/ hardware assisted application code and data protection architecture (CHCDP) to monitor the execution of application. The compiler extracts the control flow and static data integrity validation information using hashing and cyclical redundancy check (CRC) integrity algorithms at compile time. The dynamic data integrity validation is generated in the process of application execution. Likewise, the function return address and frame point are also protected at runtime. The designed hardware observes its dynamic execution trace and checks whether the trace conforms to the permissible behavior. And it will trigger appropriate response mechanisms if finding a mismatch. An OR1200 processor is assigned to build a System on a Programmable Chip (SOPC) that implements the architectural design. The experimental analysis shows that the proposed techniques can eliminate a wide range of common software and physical attacks with low performance penalties and minimal overheads. ©2009 IEEE.

Modelling of ultrasonic motor with dead-zone based on Hammerstein model structure

引用

Journal of Zhejiang university-Science A(Applied Physics & engineering) 2008年第1期9卷 58-64页

作者： Xin-liang ZHANG Yong-hong TAN Department of Automation School of Electronic Information and Electrical Engineering Shanghai Jiao Tong University Shanghai 200030 China Laboratory of Intelligent Systems and Control Engineering Guilin University of Electronic Technology Guilin 541004 China

The ultrasonic motor (USM) possesses heavy nonlinearities which vary with driving conditions and load-dependent characteristics such as the dead-zone. In this paper, an identification method for the rotary travelling-wave type ultrasonic motor (RTWUSM) with dead-zone is proposed based on a modified Hammerstein model structure. The driving voltage contributing effect on the nonlinearities of the RTWUSM was transformed to the change of dynamic parameters against the driving voltage. The dead-zone of the RTWUSM is identified based upon the above transformation. Experiment results showed good agreement be- tween the output of the proposed model and actual measured output.

A neural model for hysteresis based on expanded input space is proposed in this article. In this method, the behavior of hysteresis is considered as a dynamic system that can be described by a nonlinear state space equation containing hysteretic state. In order to transfer the multi-valued mapping of hysteresis into a one-to-one mapping, an expanded input space involving the original input variable and a so-called Duhem operator is constructed. Thus, the neural networks can be employed to approximate the relation between the hysteretic state and the output of the system that is also the output of hysteresis. The proposed model has a simple architecture that can be easily implemented for on-line adaptation for the model in case of the unexpected change of operating environment. Furthermore, the dynamic performance of the model is improved because of the existence of Duhem operator. Finally, the method is used to the modeling of hysteresis in a piezoelectric actuator. © 2007 IEEE.
