The purpose of research- the developing of a new methodology of structural - algorithmic synthesis of AC and DC electric drives optimal control. The mentioned methodology can be provide high dynamic and static characteristics, low sensitivity to parametric and coordinate disturbances, and increased energy performance in sliding modes of different orders. The methods of research - the linear quadratic optimization of optimal regulators with using perturbed - undisturbed movement concepts, inverse dynamics problems and second Lyapunov method; mathematical modeling and simulation. The proposed approach, based on modifying symmetry principle, let us determine a clear dependences between control object's parameters, Lyapunov function for the closed loop system and coast function parameters. These dependencies let us construct a controller which guarantees aperiodic transition controlled movement. This controlled movement performed with the given constraints maximum level speed of a control action. The synthesis and research of discontinuous control systems in the sliding mode DC electric drive, vector control of induction motors, double feed induction motors and asynchronous valve cascade, control system of elastic - dissipative electromechanical objects with irrational activation function.
