Design and control of an active ankle-foot orthosis
… two methods are proposed. First, an adaptive extended state observer is developed to reject disturbance and estimate the error in the dynamics model. Second, a nonlinear model predictive controller is presented to track the ankle trajectory while reducing assistance to the user. The adaptive …

Structure-Inspired Disturbance Observer Design and Disturbance Observer-Based Control/estimation
… two topics: (1) structure-inspired disturbance observer design and (2) disturbance observer-based control/estimation. The disturbance is defined as the discrepancy between a model and the system the model represents. A disturbance observer is an algorithm that generates an estimate of the …

Observer based active fault tolerant control of descriptor systems
… as separate design issues often using a standard state space (i.e. non-descriptor) system model approach. These separate FDD/FE and reconfigurable control designs may not achieve desired stability and robustness performance when combined within a closed-loop system.This work describes a new …

Design and Control of A Ropeless Elevator with Linear Switched Reluctance Motor Drive Actuation Systems
… extra hardware. The controller is based on an extended state observer (ESO) and a nonlinear P controller (NLP). The proposed method does not require an accurate mathematical model of system and can be implemented on a low-cost DSP controller. The proposed ESO is exploited to estimate the …
