Nonlinear transformation theory has been used in the design of the control system to represent nonlinearities in the model of the system. The singular perturbation theory is used to simplify control system structure and a new algorithm has been synthesized for the inverse nonlinear transformation of the control terms. Problem of modeling errors in the system with nonlinear inverse dynamics theory is investigated. The results of simulation show that the control system could track commanded values under the presence of modeling errors and disturbances.","PeriodicalId":344374,"journal":{"name":"SICE '95.

In real situations including computer simulations, however, the generated guidance commands are applied to a full rigid body model. This can cause attitude instability of the vehicle. In this paper, the effect of the guidance commands, generated from a point mass model, on the full rigid body model is analyzed quantitatively, and an attitude stabilizing strategy is proposed. An attitude stabilizing condition for the rigid body model is derived by using the Lyapunov stability theorem. The stabilizing condition derived can be used to stabilize the attitude of a launch vehicle by applying the corresponding feedforward guidance commands when the commands generated from a point mass model destabilize or undetermine the attitude of a launch vehicle. Computer simulations have been performed to verify our conjecture for the second stage of the Japanese N-I launch vehicle.","PeriodicalId":344374,"journal":{"name":"SICE '95.

We study a practical and mobile subsea locomotion mechanism which makes robots land speedily and softly on the surface of the structure. And this mechanism can maintain a stable position and orientation for the robot working at subsea conditions by moving the robot body in a pendulum-like motion under the cooperative control of the propellers and the leg. We describe the technology of this locomotion mechanism for subsea robots and demonstrate the effect of this mechanism through a simulation study.","PeriodicalId":344374,"journal":{"name":"SICE '95.

The spinning effect of the vehicle is to average the uncertain aerodynamic force and give the stability by its gyro momentum. However, the missile spin axis has the minimum moment of inertia, therefore the induced nutation will diverge unless it is actively dumped. The principle of the induction of the nutation and its active damping algorithm are explained first. An attitude control system of a missile by gas jet impulses is designed and simulations are conducted. The result showed fine performance. However, in a practical application, many problems are left to be solved.","PeriodicalId":344374,"journal":{"name":"SICE '95. Proceedings of the 34th SICE Annual Conference.

The increase in nonlinear resistive component elevated the pressure and depressed the flow. Intense minimization of the linear and nonlinear terms involving the absolute driving airway pressure depressed rapid increase in pressure and peak flow rate. They have a greater effect on airway pressure and flow than any other terms such as absolute lung volume, its rate of change, the rate of change in pressure, or their related nonlinear terms. These nonlinear factors are necessary and indispensable to be controlled to produce physiological respiration.","PeriodicalId":344374,"journal":{"name":"SICE '95.

The behavior of life is complex and interesting. All life must have some intelligence for making its own life cycle stable and adept to changing environment. This study tries to model mathematically the formation of a specific part of living cells. For this purpose, we prepare an adequate mathematical model of physical interactions on many different properties. The mathematical model presents parallel distributed processing system that exchanges information through vibrating potential field (VPF) and life's kinetics. Using VPF and life's kinetics, the computer simulations show the behaviors of artificial life that conserves its own energy level and tunes its configurations or location of its parts.","PeriodicalId":344374,"journal":{"name":"SICE '95.

The mean travel time is evaluated by taking account of traffic congestion lengths, traffic signal control parameters, moving directions at the downstream signalized intersection and so on.
