Abstract: The amplitude, frequency and energy dissipation of oscillations caused by the presence of a second order actuators in the systems driven by main sliding mode controllers are analyzed.
The aim of this note is to investigate the chattering in main SMC algorithms when a parasitic dynamic is introduced in the control loop. Also we analyze the ...

Oct 22, 2024 · Chattering is a harmful phenomenon because it leads to low control accuracy, high wear of moving mechanical parts, and high heat losses in power circuits.
These adaptation laws explicitly aim to avoid the overestimation of the control gain to reduce the chattering, and to guarantee SMC accuracy—i.e., drive the ...
