Improved Rotor Flux-Based SMO and RBF-PID Control Strategy for PMSM

Actuators, 2023
This paper proposes a control strategy that combines an improved flux-based sliding mode observer with a Radial Basis Function Proportional-Integral-Derivative (RBF-PID) controller for the control of Permanent Magnet Synchronous Motors (PMSM).

State and unknown input estimation in a CSTR using higher-order sliding mode observer [PDF]

, 2011
The aim of this paper is to design and analyze an observer based on high-order sliding mode to estimate states and unknown inputs in a continuous stirred tank reactor (CSTR). Additionally, the designed HOSM allows to reduce the chattering.

Output feedback sliding mode control based on adaptive sliding mode disturbance observer

Measurement and Control, 2022
In this paper, an adaptive sliding mode disturbance observer is designed to counteract the disturbance actively. By designing the adaptive laws, the assumptions on the disturbance are relaxed in the proposed observer, its first derivative upper bound is considered to be unknown.
