The common experience in solving control problems shows that
optimal control as a function of time proves to be piecewise
analytic, having a finite number of jumps (called switches) on any
finite-time interval. Meanwhile there exists an old example
proposed by A.T. Fuller [1961) in which optimal control has an
infinite number of switches on a finite-time interval. This
phenomenon is called chattering. It has become increasingly clear
that chattering is widespread. This book is devoted to its
exploration. Chattering obstructs the direct use of Pontryagin's
maximum principle because of the lack of a nonzero-length interval
with a continuous control function. That is why the common
experience appears misleading. It is the hidden symmetry of
Fuller's problem that allows the explicit solution. Namely, there
exists a one-parameter group which respects the optimal
trajectories of the problem. When published in 1961, Fuller's
example incited curiosity, but it was considered only "interesting"
and soon was forgotten. The second wave of attention to chattering
was raised about 12 years later when several other examples with
optimal chattering trajectories were 1 found. All these examples
were two-dimensional with the one-parameter group of symmetries.
