Extended-State-Observer-Based Super Twisting Control for Pneumatic Muscle Actuators

Actuators, 2021
This paper presents a tracking control method for pneumatic muscle actuators (PMAs). Considering that the PMA platform only feedbacks position, and the velocity and disturbances cannot be observed directly, we use the extended-state-observer (ESO) for ...

Hybrid NMPC-ESO-PINSE Approach for Liquid Level Control in a Nonlinear Four-Tank System: Integration of Deep Learning and Extended State Observation Under Stochastic Uncertainties

Automation
Liquid storage tanks are widely used in sectors such as water treatment, oil and gas, food processing, and chemical manufacturing. Knowing the exact amount of liquid in a tank is essential for ensuring safety, preventing spills, and optimizing process control; therefore, the liquid level in a tank must be maintained at a precise reference point.
