Control and management of the urban traffic signal is an problem that modern city has to face. The traffic signal controller makes a great contribution to the improvement of traffic status and the reduction of traffic jam. A traffic controller is designed using the technology of USB host based on ISP1161A. Universal serial bus is new interface bus architecture for PC
which supports the PnP function Of PC peripheral equipments and has been widely used in computer and communicational devices. ISP1161A complies with the protocol of USB1.1
and is used as the core part of the system. As a new try
the USB host technology is applied into the design of controller to implement the communication with PC. Configuration of scheme is carried out successfully. The USB host technology makes configuration of scheme and future update easier and more convenient. 2011 IEEE.

The common bus on bus control is RS232. With the development of field bus technology
field bus technology is widely used in data recorder. How to real time record the data of field bus in the experiment and provide the test data for process reconstruction is a very important problem. This paper introduces a kind of data acquisition and storage based on field bus. Its core design is C8051F040 microprocessor and SJA1000
a widely used field bus controller. This paper presents the basic constitution of this field bus data recorder and set forth its hardware and software. This field bus data recorder field bus real-time gathers the information and storage data on the CF card. The result of the experiment shows the system is highly reliable for data acquisition and storage
which should have abroad application prospect for data record experiment. 2010 IEEE.

The variable time delay and the packet loss degrade the performance of Internet based teleoperation system seriously
even make the system unstable. To overcome the trouble
an idea that using CARIMA model of the linearized slave robot to design a controller based on the Generalized Predictive Control (GPC) method is proposed in this paper. We place the GPC controller at the remote site. First of all
The CARIMA model of the linearized slave robot is derived. Secondly
a GPC controller is designed at slave site to generate the redundant control information to diminish the influence of the packet loss and the large time delay in the internet to the system. Moreover
in order to solve the problem caused by the variable time delay
the reference information signed with time stamp is used and fedback to the operator
so the operator can predict the next round trip time delay(RTT) according to the preceding RTT we got. Finally
stability condition is achieved. Simulation results show that these strategies can dynamically compensate for the variable time delay and reduce the performance degradation induced by packet loss.

Fuzzy controller was used to resolve the problem of fast tracking and overshoot in electric-driven simulation turntable
for its essence belongs to PD control In this system
the control rules of fuzzy controller were established according to the step dynamic response process
for the speed loop of this system was predigested to be second-orders system. The describing function method was adopted to analyze the stability of the fuzzy control system. It gave the information of stability of system intuitively. The fuzzy controller had been applied in this system successfully. The simulation turntable had no overshooting nearly when its step input signal was close to 90. Experimental results show the implementation method of fuzzy controller is not only simple but also effectual in engineering practice. It also provides an approach of design of fuzzy controller for motion control system. 2008 IEEE.
