A Numerical Approach forTime - Optimal Control of Double Arms

چکیده

Time-optimal nonlinear control of rest to rest maneuvers of double arms robot is solved using Pontryagin's Minimum Principle. A numerical non-optimal solution satisfying the state equations with the initial and the nal boundary conditions is found and used to obtain a good approximation of the initial values of the costates. Then the corresponding nonlinear two-point boundary-value problem is solved by applying a shooting method. A good approximation of the initial costate is usually needed to make the shooting method converge. This initial guess is generated here by the forward-backward method. A strategy that combines the shooting method and the forward-backward method to time-optimal control of the double arms robot is illustrated by the numerical examples .

Optimal Control of Service Rate in a Service Center with Lapse (Research Note)

The purpose of this paper is to analyze the effect of a particular control doctrine applied to the service mechanism of a queuing process with lapse. It is assumed that the service discipline is FCFS (first come, first served), arrival process is Poisson, service time distribution is exponential, service process is one phase and the capacity is infinite. It is also assumed that the customer may...
