Nonlinear controller design: an iterative relaxation method

Analytical design of optimal controllers for nonlinear systems is studied. To refine the method related to minimization of the general work functional, the initial control problem is transformed to a degenerate problem and solved with a suitable strategy. The joint control design strategy is the construction of minimizing sequences, which converge in intervals by stationarity to the optimal process of the initial problem. An illustrative example is given.
