— The max-plus linear systems have been studied for almost three decades, however, a well-established system theory on such specific systems is still an ongoing research. The geometric control theory in particular was proposed as the future direction for max-plus linear systems by Cohen et al. This paper reports upon recent investigations on the disturbance(More)
— This paper presents an integrated control strategy solving disturbance decoupling of max-plus linear systems. The classical disturbance decoupling problem (DDP) in geometric control theory means that the controlled outputs will not be changed by any disturbances. The DDP problem has no practical meaning in the context of Max-plus system, since the(More)
— This paper presents a sufficient condition to solve the observation problem in tropical linear event-invariant dynamical systems, where a linear functional of the states can be observed in a finite number of steps using only the information from inputs and outputs. Using the residuation theory, this solvability condition can be easily implemented in(More)
We propose a random search algorithm to resolve the problem of packing circles into a rectangular container. With our method, all the circles are put into a large space randomly, and then by introducing the bow shift area, the searching space can be reduced and the local optimal solution can be list. By moving, turning and other disturbance methods, it will(More)
