SYNTHESIS OF FOURTH-ORDER SLIDING MODE CONTROL SYSTEM BY N-i SWITCHING METHOD WITH CONDITION OF UNCERTAIN MAXIMUM OF FIRST AND SECOND DERIVATIVES OF OPERATED COORDINATE

Conformably to fourth-order sliding mode control system was obtained the correlation for maximum values of first and second derivatives of operated coordinate with sudden change of master control. The bounds of control action range were defined, which provides realization of prescribed form of transient, optimal in time domain. The procedure of synthesis for sliding mode subordinated control system was expounded.
