Energetic Optimization with Arbitrary Terminal Moment of Electric Drives Systems

Boteanu Niculae, Popescu Marius-Constantin, Ravigan Florin
In the paper we consider an electric drive having static load torque with a constant component and a speed proportional component, in the hypothesis of constant inertia moment and of proportionality between the electromagnetic torque and the load current. Using variational calculus, optimally condition and expression of optimal control and extremal trajectory are determined, which ensures the minimum of energy losses caused by the load current through a Joule effect in the acceleration
