The features of variable structure system application in conditions of control signal saturation

The variable structure system with control signal saturation for the position control of second order dynamic object is considered in this paper. The features of system phase trajectories and transition processes at different values of control law coefficients are analyzed. The new conditions of a sliding mode existence in the given areas of a phase plane are formulated. The control systems parameters ensuring the greatest possible fast-action and high dynamic precision are determined. The received conclusions are confirmed by results of control system numerical simulation.
