document: Synthesis of the control systems via reflection onto auxiliary surfaces An approach to robust control systems synthesis , both linear and nonlinear , and nonstationary is offered . The control is carried out , providing the given phase constraints varied in acceptable limits , in view of constraints on its value and incompleteness of the information about functioning disturbances . The approach is based on the introduction of auxiliary integral surfaces , on which the initial moving is projected . As a result the reduced equivalent moving is formed , being described by the scalar equation which in many important cases can be integrated directly . On the basis of the equation obtained solving a synthesis task is carried out and can be reduced to algebraic or integral inequalities . The final relations defined for linear equivalent moving are presented
