Tracking System Design Based on Digital Minimum Variance Control with Fuzzy Sliding Mode

This paper deals with the design of digital fuzzy sliding mode control where only the plant output is used for the realization of control algorithm. The suggested concept is based on minimum variance control approach with disturbance estimator. The additional filtration of nonlinear, fuzzy, control component is performed by using the digital integrator. The higher accuracy in steady-state is also reached for a size range relative to the existing solutions.
