Abstract
Pontryagin’s Minimum Principle is a way of solving hybrid powertrain
optimal energy management. This paper presents an improvement of a
classical implementation. The core of this improvement consists in
relaxing the tolerance on some intermediate steps of the algorithm in
order to reduce the number of iterations and thereby reducing the number
of operations required to compute an optimal solution. The paper
describes both a classical implementation of Pontryagin’s Minimum
Principle as well as the improved version. Numerical simulations are
conducted on an academic example to demonstrate the benefits of the
proposed approach.
