A Bernoulli Tau method for numerical solution of feedback Nash differential games with an error estimation

In the present study, an eficient combination of the Tau method with the Bernoulli polynomials is proposed for computing the Feedback Nash equilibrium in differential games over a finite horizon. By this approach, the system of Hamilton-Jacobi-Bellman equations of a differential game derived from Bellman s optimality principle is transferred to a nonlinear system of algebraic equations solvable by using Newton s iteration method. Some illustrative examples are provided to show the accuracy and eficiency of the proposed numerical method.
