CHATTERING-FREE VARIABLE STRUCTURE CONTROL

Ján Kardoš

   This paper deals with a chattering-free modification of the t-suboptimal position control, ie the robustified t-optimal fixed target control. We present an equivalent control approach synthesis witch satisfies the reaching condition and eliminates the problem of discontinuous control - the high-frequency oscillations. Simulations show both fast and robust resultant overshoot free responses despite the presence of parametric disturbances.
