Sliding mode control with adaptive vss observer

Electrical Engineering in Japan, 1991
AbstractThe conventional sliding mode control or variable structure control (VSC) of a nonlinear uncertain system is well known for its robust property and simplicity of control law. However, the use of either is permitted only on the assumption that the upper bound of parameter variation or nonlinearity is known and that the complete information about

Research on Control Strategy of Permanent Magnet Synchronous Motor Based on Fast Terminal Super-Twisting Sliding Mode Observer

IEEE Access
The sliding mode observer (SMO) has the advantages of small influence by parameter changes and strong robustness, which is widely used in the sensorless control of permanent magnet synchronous motor (PMSM). However, when the sliding mode observer is used

A Sliding Mode-Multimodel Control with Sliding Mode Observer for a Sensorless Pumping System

CoRR, 2013
This work deals with the design of a sliding mode observer with a multi-surfaces sliding mode multimodel control (SM-MMC) for a mechanical sensorless pumping system. The observer is designed to estimate the speed and the mechanical position of the DC motor operating in the process.
