Numerical Solution of Optimal Trajectories for Fully Actuated Mechanical Systems

We describe a numerical method for computing optimal trajectories for fully actuated mechanical systems. This method uses the fact that fully actuated mechanical systems are diierentially at with conngura-tion variables as at outputs to parametrize the system trajectories by connguration space trajectories. Our approach has the advantage that the system ODEs are implicitly satissed and hence we...

A Numerical Solution of Fractional Optimal Control Problems Using Spectral Method and Hybrid Functions

In this paper‎, ‎a modern method is presented to solve a class of fractional optimal control problems (FOCPs) indirectly‎. ‎First‎, ‎the necessary optimality conditions for the FOCP are obtained in the form of two fractional differential equations (FDEs)‎. ‎Then‎, ‎the unknown functions are approximated by the hybrid functions‎, ‎including Bernoulli polynomials and Block-pulse functions based o...

The Numerical Solution of Some Optimal Control Systems with Constant and Pantograph Delays via Bernstein Polynomials

‎In this paper‎, ‎we present a numerical method based on Bernstein polynomials to solve optimal control systems with constant and pantograph delays‎. ‎Constant or pantograph delays may appear in state-control or both‎. ‎We derive delay operational matrix and pantograph operational matrix for Bernstein polynomials then‎, ‎these are utilized to reduce the solution of optimal control with constant...
