Periodical Modes in the Combined Nonlinear Control Systems for One Class of Non-Affine Dynamic Plants

The dynamic processes which occurs in the nonlinear control systems of input non-affine stationary dynamic plants operating in a priori parametric uncertainty and under constant action of the external disturbances are considered. As the methods of synthesis of the control systems hyperstability criterion, fast-acting dynamic corrector and L-dissipativity conditions are used. With the help of simulation modeling, the quality of work of two control systems (system with a combined non-linear controller and a system with a non-linear-periodic control loop) is illustrated and compared. The obtained results may be useful to construct the control systems for various technical plants which functioning in periodic modes (for example for controlling the manipulation robots, rotor systems etc.).
