병렬 로봇을 이용한 객실의 능동 제어 기법 적용에 관한 연구
신찬배,심호석 울산과학대학 2004 연구논문집 Vol.31 No.1
본 연구는 각종 운송 수단에서 이동시 발생하는 진동이 객실 등에 전달되는 것을 방지하기 위해 3RRR타입의 병렬 로봇을 이용하여 능동제어를 실시한 것이다. 운송시스템의 정확한 절대적 위치를 모르는 상태에서 속도 및 가속도 값만을 피드백하여 진동을 감쇠하였으며 그 결과 운송시스템에서 발생하는 진동을 최대 8배까지 감쇠할 수 있었다. The desire for the stable and comfortable cabin of the high speed transport system is increasing. In this study, a new control system operated by 3RRR parallel robots such as the active suspension system of motor vehicle is proposed. The goal of this control is keeping zero velocity of the upper robot(cabin) although the lower robot(transport system) is moving randomly. Jacobian matrix was used to design the controller. From the simulation results, the remarkable reduction of motion of the cabin(upper platform) was observed.

This paper presents a robust position control of a ball & beam system Via LQG/LTR. The LQG/LTR design methodology is a systematic design procedure for designing high performance feedback control systems for both single-input and single-output(SISO) and multi-input and multi-output(MIMO) systems. It allows one to design a set of frequency domain specifications chosen appropriately for desirable command following and disturbance rejection properties with low sensitivity to modeling errors and sensor noise. It is found that the LQG/LTR design method has good performance in comparision with the classical control(PID-control) design method.

Pneumatic cylinder actuators are significantly utilized for industry automatic systems in the fields of mechanical applications. We propose a novel control method for pneumatic cylinder actuator systems including stochastic friction dynamics. The proposed control mechanism is linearly composed of nominal control and auxiliary control variables. The former is designed from linear system model without friction terms by using a previous linear system theory and the latter is constructed as a function of friction estimation which is carried out by a well-known least square algorithm for reducing the control error due to random friction dynamics. We accomplish numerical simulation to demonstrate reliability of the proposed control method and conduct a comparative study to improve its superiority.

신찬배,이상화 울산과학대학 2003 연구논문집 Vol.29 No.2
차종마다의 다양한 Tail Gate의 특성에 의해서 Gas Spring을 적용하기 위해서는 많은 문제점을 가지고 있다. 이 논문에서는 Tail Gate와 Gas Spring 사이의 일반적인 관계를 규명하고 향후 개발될 차종에 적용 가능한 설계방법을 제시한다. With the characteristics of various vehicle's tail gates, there are a lot of problems to adapt gas spring. In this paper, we prove the general relations between the tail gate and the gas spring and suggest an adaptive design method.

The heat transfer model of ondol heating system is derived in the linear form. The step responses of On-Off controller, PID controller and Position type fuzzy controllers are compared in the sense of several aspects : variation of temperature feedback variable, variation of supplied heat quantity by the boiler, variation of flow rate, variation of thickness of the base, variation of the outdoor temperature.

In this paper we present a new visual approach for the robust bin-picking in a two-step concept for a vision driven automatic handling robot. The technology described here is based on two types of sensors: 3D laser scanner and CCD video camera. The geometry and pose(position and orientation) information of bin contents was reconstructed from the camera and laser sensor, these information can be employed to guide the robotic arm. A new thinning algorithm and constrained hough transform method is also explained in this paper. Consequently, the developed bin-picking demonstrate the successful operation with 3D hole object.
