Compositional synthesis of time-suboptimal control of higher-order systems

It is offered approximate approach to time-suboptimal control for smooth stationary systems with phase constraints are considered. This approach associated with the feedback realization of time-suboptimal control nonlinear systems. The efficiency of the method allows synthesize suboptimal control law by optimal control law of lower systems. In the general case, this approach allows realize compositional synthesis of all nonlinear control systems by effective and reliable results of optimal dynamic systems first order.
