Sliding Mode Speed Control for Induction Motor Drives with State-Dependent Gain Method

The main obstacle of conventional sliding mode control is caused by discontinuous function of high control activity which is known as chattering phenomenon. In this research, the chattering phenomenon is significantly reduced by a newly developed algorithm. A fast sigmoid function with varying bound...
