궤도차량의 실시간 동적 시뮬레이션을 위한 이산시간 능동현가장치 제어

In this research, the discrete time control algorithm for the active suspension system of a tracked vehicle is utilized to analyse the relation between the simulation error and the length of sampling time. Simulation results obtained by discrete time algorithm are verified by those obtained by continuous time algorithm and compared to analyse the computation error caused by changing the length of sampling time. 1-2 msec is the maximum length of sampling time to tolerate computation error. Therefore the computation for one step in real time simulation should be completed within at least 1-2 msec.
