New compound control algorithm in sliding mode control to reduce the chattering phenomenon: experimental validation

Abstract: In this work, a new SMS is proposed to achieve high tracking and suitable robustness. However, the chattering phenomenon should be regarded as the main drawback of the SMC. Therefore, a new compound control algorithm is used for reducing the chattering phenomenon. The applied compound control law constantly evaluates the error and send the correct value to the system. This significantly will reduce the chattering phenomenon. The performance of the control methods validated by applying on a robot arm experimentally.
