Algorithms for chattering reduction in system control

► A method for determining the sliding gain function in the Sliding Mode Control (SMC). ► Two tuning algorithms for reducing the sliding gain function for nonlinear systems. ► The performance of the algorithms is evaluated for six different cases. ► A 90-95% reduction of chattering is achieved for systems with sensor dynamics only. ► Chattering is reduced by 70-90% for systems with noise and/or disturbance.
