Robust Iterative Learning Control for output tracking via chattering-free sliding mode control technique

Performance evaluation of iterative learning control with different sliding mode algorithms for the slip‐ratio control of an electric vehicle

“…The selection of sliding surface $$$ {S}_k(t) $$$ and developing a control input signal $$$ {u}_k(t) $$$ by iterative mechanism are two essential steps that have to surmount. In reference to Reference 11, $$$ {S}_k(t) $$$ is the sliding surface dynamics at $$$ k\mathrm{th} $$$ iteration and $$$ {u}_k(t) $$$ is the SMC‐ILC control input at $$$ k\mathrm{th} $$$ iteration.…”

“…LVSC controllers have been used in a variety of applications, including torque-ripple reduction in permanent magnet synchronous motor, 7 control of Czochralski process in semiconductor industry, 8 electro-pneumatic, 9 quadrotor UAVs, 10 and so on. [11][12][13][14] provide research publications on the ILC-SMC combo. However, control input discontinuities causes chattering and produces inconsistent control action.…”

“…Continuous SMC was created in Reference 6 to alleviate the chattering difficulty by providing an integration approach, although it was not a learning control. LVSC controllers have been used in a variety of applications, including torque‐ripple reduction in permanent magnet synchronous motor, 7 control of Czochralski process in semiconductor industry, 8 electro‐pneumatic, 9 quadrotor UAVs, 10 and so on 11‐14 . provide research publications on the ILC‐SMC combo.…”

Robust iterative learning control design based on iterative integral sliding mode for nonlinear systems with unrepeatable disturbance

“…Ding and Yang (2014) proposed a RILC design using a SOSM technique. Liu et al (2010) combined the continuous SMC with ILC scheme. Yan et al (2018) proposed to combine the ILC design with a terminal sliding mode (TSM), which can achieve the fast converging and the control robustness.…”
