Observed convergence of location hypothesis Conclusions A logical sparsely connected autoassociative network (GNU) was used to model homing behaviour of an organism in an environmental simulation. Three phases of homing behaviour were identified in the simulation results. A location error measure was proposed that was seen to characterise the different phases of homing behav...

Optimal feedback-control laws generally cannot be obtained in closed form for stochastic control problems. The characterizations which have been obtained for several simplified problems have provided valuable insight into the properties of optimal feedback-control laws as well as providing guidance for the construction of suboptimal control laws. In this paper an analytical and computer simulat...

Abstract: The paper studies the problem of finite time formation control for multiple vehicles based on the motion planning approach. The vehicle is modeled as the full actuated rigid body with the dynamics evolving on the tangent bundle of Euclidean group, both the formation time which is finite and the geometric structure of the formation are assumed to be specified by the task. For the requi...

In an earlier study, presented at the 3 rd EUCASS [1], an innovative guidance strategy was outlined by integrating the design of a multiple model adaptive estimator and a differential game based guidance law. Such strategy indicated two potential breakthroughs in the interception of randomly maneuvering targets in Ballistic Missile Defense. Further studies indicated that while the differential ...

Interception problems are often dealt with by separating guidance and autopilot design. Guidance law can be obtained using optimal control theory and autopilot design is performed on a linearized system. In this paper, we introduce a new approach that determines a global guidance and autopilot law, based on direct output feedback design. Application of this method to exoatmospheric interception...

In this thesis, we study formation control and guidance algorithms using only bearing measurements. First, an angle based leader–follower formation control problem is considered. In this problem, there are three leaders which have access to their own global positions. The other agents are followers which sense relative bearing measurements with regard to three neighbors. We propose a control st...

With the combination of the model reference adaptive control and iterative learning control, a model reference adaptive iterative learning control algorithm was proposed for a class of first order linear time-varying systems which are BIBO stable and repeatable in a finite time interval . By means of Lyapunov technique , an iterative learning control law with adaptive update law for time-varyin...
