TO THE COMPUTATION OF NONLINEAR CONTROL SYSTEMS APPLlCATION OF THE MULTI-LEVEL SUBSTRUCTURAL METHOD

The multi-level substructural method is one of the most extensively usedmethods in the program system of computational structural mechanics.Bajsed on similaritiesbetween computational structure mechanics and optimal contro1,the problem in nonIinearcontrol system is computed by using the same method,and the corresponding program isgiven.The work in this paper further shows the close similarity betWeen computationalstructure mechanics and optimaJ control.
