| Summary: | We introduce a formulation for the time-optimal control
problems of systems displaying fractional dynamics in the sense of the
Riemann-Liouville fractional derivatives operator. To propose a solution
to the general time-optimal problem, a rational approximation based on
the Hankel data matrix of the impulse response is considered to emulate
the behavior of the fractional differentiation operator. The original problem is then reformulated according to the new model which can be solved
by traditional optimal control problem solvers. The time-optimal problem is extensively investigated for a double fractional integrator and its
solution is obtained using either numerical optimization time-domain
analysis. |
