이만형,H. M. LEE,K. S. LEE,S. K. HA,J. I. BAE,J. H. PARK,박형규,H. J. CHOI,전호환 한국자동차공학회 2011 International journal of automotive technology Vol.12 No.5
In this paper, a hardware-in-the-loop simulation (HILS) system was developed before the development of an electric power steering (EPS) system in a vehicle. This study was focused on the establishment of the HILS system. Driving conditions are simulated with the HILS system. The actual steering input parameters are confirmed on the monitor while driving the HILS system. The steering forces observed in the simulation with the developed HILS system are similar to those in real vehicle tests. The developed HILS system can be applied in the development of various types of EPS systems.

The authors adopt heterarchy mode of Regional Innovation System (RIS) governance mechanism to account for economic ups and downs of Route 128 centered on Greater Boston. We believe that heterarchical type of governance would provide a vantage point through which to view how micro-level performances become translated into macro-level patterns and, in turn, how the macroscopic patterns feed back into micro-level performances. Although most of existing studies rely heavily on the elite model in explaining the role of academia, we attribute the economic revival of Route 128 since the late 1990s to the diffusion-oriented education model. In addition, the inter-organizational collaboration in this region has taken place not within the same industrial sector tied into a single technological trajectory but across sectors with different technologies. Although our exploration of inter-systemic steering is still under way and requires thorough investigation, we believe that Route 128's economy must be understood in a broader global context because its overall system has been more influenced by changes in world politics and economy than its counterparts in other domestic regions and overseas.

In this paper, the depth controller of an underwater vehicle based on an $H_\infty$ servo control is designed for the depth keeping of the underwater vehicle under wave disturbances. The depth controller is designed in the form of the $H_\infty$ servo controller, which has robust tracking property, and an $H_\infty$ servo problem is considered for the $H_\infty$ servo controller design. In order to solve the $H_\infty$ servo problem for the underwater vehicle, this problem is modified as an $H_\infty$ control problem for the generalized plant that includes a reference input mode, and a suboptimal solution that satisfies a given performance criteria is calculated with the LMI (Linear Matrix Inequality) approach. The $H_\infty$ servo controller is designed to have robust stability about the perturbation of the parameters of the underwater vehicle and the robust tracking property of the underwater vehicle depth under wave force and moment disturbances. The performance, robustness about the uncertainties, and depth tracking property, of the designed depth controller is evaluated by computer simulation, and finally these simulation results show the usefulness and applicability of the proposed $H_\infty$ depth control system.
