Chattering Problem in Sliding Mode Control Systems

WebThe chattering phenomenon [12], which is caused by the unmodelled dynamics system (the phenomenon that is affected by the controller and external perturbation that are not observable by the model), is the main drawback of the SMC. Chattering is a quick, sometimes noisy vibration with a fixed frequency and amplitude. WebIn order to reduce the chattering caused by the discontinuity of the control function in the traditional sliding mode observer (SMO), this article proposes a sliding mode observer with phase-locked loop (PLL) to estimate the speed and position of the rotor. laptops for low price
