| In this paper, optimal control problems considering agile turn of missile as maximizing terminal velocity at boost phase are dealt. The missile in the phase experiences dramatic variation in velocity, mass and angle of attack within finite duration. This research at first, classifies the missile models into two different cases; longitudinal motion and lateral motion, but all of the models neglect aerodynamic forces. Each model has an optimal solution known as Bang-Singular Control, and the corresponding optimal control as well as switching condition for Bang to Singular is analytically derived |

Observer Motion Controls for Multiple Targets Considering Doppler-Bearing Measurements |
|
Jonghoek Kim, Taeil Suh, Jonha Ryu(Agency for Defense Development, Korea) |
| The DBTMA problem is to estimate the position and velocity of a target using both frequency
and bearing measurements. As the method to increase the estimation accuracy in the DBTMA problem, this paper introduces observer motion controls under the following motion constraints: the observer moves with a constant speed, and the turn rate of the observer is upper bounded by a certain maximum turn rate. We verify the effectiveness of our observer motion
controls using MATLAB simulations.

Terrain relative navigation for precise lunar landing using crater matching algorithm |
|
Woosang Park, Youeyun Jung, Hyochoong Bang(KAIST, Korea) |
| It is difficult to perform a precise inertial navigation without GPS. Under GPS-denied conditions, an inertial navigation diverges easily due to integration drift in the measurement of acceleration and angular velocity. Therefore, a terrain relative navigation (TRN) is applied to correct the drift error for precise lunar landing mission. In this paper, crater matching algorithm based on conic-pair invariants is used to collect INS drift error. And the navigation performance is analyzed by MATLAB simulation. |

Optimal Design on Policies of Industrial Eco-Economic System in China under the Constraint of Energy Saving and Carbon Emission |
|
Yingbo Qin, Wenping Wang, Wenwen Li(Southeast University, China) |
| With the purpose of resolving contradiction between economic growth and environmental deterioration, this paper, using carbon emission as an example, analyzes the key factors in current industry policies, builds a model for system dynamics, simulates the impacts of different policies on the economy, energy and environment under various scenarios, and gives suggestions on the optimal design of policies. Industrial structure and energy taxation according to prices are more helpful in economy. While, carbon tax and energy structure are the most significant factors in changing carbon intensity. |

|
Vittaya Tipsuwanporn, Nurawit Oranpaiboon, Viriya Krongratana(King Mongkut's Institute of Technology Ladkrabang, Thailand) |
| The purpose of this paper is to find out the method for constructing heat exchanger model that is a mathematical model comparing with balance energy technique. Firstly, the energy balance applies energy laws for calculating energy between hot and cold side of temperature which is the energy of input equal to energy of output and the result of this process is the outcome temperature would increase further to energy power that heater provides from hot side of heat exchanger. Secondly, Mathematical Model is related to using equations of thermal and finding transferred functions of system and vari |

Teerawat Thepmanee, Prasit Julsereewong, Jirawat Poomhuang(King Mongkut’s Institute of Technology Ladkrabang, Thailand) |
| This paper addresses the design of functional safety model for process automation in accord with IEC 61508/61511 standard. Functional safety design of a tail gas treating unit has been conducted in this study. The quantitative fault tree analysis approach which has been proved to be acceptable and widely applied in many applications of modeling and methods supporting the designer and safety engineer not only to identify how subsystems and components could fail and what are the corresponding effects on the whole system, but also to quantify the reliability parameters for complex systems. |
