Modeling of a radio-controlled car with camera based on system identification
Hiroshi Kusano,Koichi Hidaka 제어로봇시스템학회 2010 제어로봇시스템학회 국제학술대회 논문집 Vol.2010 No.10
This paper describes a modeling of movement object. A auto driving of the car is studied to reduce traffic accidents and traffic jam in late years. The experiment tries there control with the radio controlled car which did movement same as a car. The control of the radio controlled car controls the steering voltage on speed uniformity this time. The control method usually uses model predictive control. The precision of the model becomes important for the model predictive control. To give the precision of model, a system model of straight line and curve line is necessary for the model of the radio controlled car. Since these movements of the radio controlled car are different, these model do not become the same models. The model of the car on curve needs closed loop identification with impossibility by open loop identification. Therefore, we examine the model of straight line using closed loop identification model to consider proper model.
Effect of thin LiF layers in multi-layered PVCz polymer LEDs
Hiroki Yoshihara,Yousuke Tanaka,Suiko Tanaka,Masahiko Kitagawa,Hiroyuki Kusano,Hiroshi Kobayashi 한국물리학회 2005 Current Applied Physics Vol.5 No.1
We have investigated in detail the dependence of the electroluminescent characteristics on the thin LiF layer inserted under theelectrode layer of multi-layered PVCz polymer light emitting diode (PLED). Clear dependency has been obtained and reduction inthe operating voltage, improvement in luminance and the luminous and current eciencies have been realized with the optimizationof the thickness. The eect of thin LiF layer has been analyzed by using the current voltage dependence at low voltage regions andthe current is supposed to be carried considered LiF layer by tunnel injection between the PVCz layer and the electrode layer
