Abstract:
In this paper, we investigate a problem of optimal control over a finite time interval for a linear system
with constant coefficients and a small parameter in the initial data in the class of piecewise continuous controls
with smooth geometric constraints. We consider a terminal convex performance index. We substantiate the limit relations
as the small parameter tends to zero for the optimal value of the performance index and for the vector generating
the optimal control in the problem. We show that the asymptotics of the solution can be of complicated nature. In
particular, it may have no expansion in the Poincaré sense in any asymptotic sequence of rational functions of the
small parameter or its logarithms.
Keywords:optimal control, terminal convex performance index, asymptotic expansion, small parameter.
