Adaptive Repetitive Control of A Linear Oscillating Motor under Periodic Hydraulic Step Load [PDF]

Sensors, 2020
A linear oscillating motor has a direct and efficient linear motion output and is widely used in linear actuation systems. The motor is often applied to compact hybrid electrohydraulic actuators to drive a linear pump. However, the periodic switch of the

Elimination of Harmonic Force and Torque in Active Magnetic Bearing Systems with Repetitive Control and Notch Filters [PDF]

Sensors, 2017
Harmonic force and torque, which are caused by rotor imbalance and sensor runout, are the dominant disturbances in active magnetic bearing (AMB) systems.

Data-enabled Predictive Repetitive Control [PDF]

2024 IEEE 63rd Conference on Decision and Control (CDC)
Many systems are subject to periodic disturbances and exhibit repetitive behaviour. Model-based repetitive control employs knowledge of such periodicity to attenuate periodic disturbances and has seen a wide range of successful industrial implementations. The aim of this paper is to develop a data-driven repetitive control method.

Current Harmonics Minimization of Permanent Magnet Synchronous Machine Based on Iterative Learning Control and Neural Networks

Machines, 2023
Electrical machines generate unwanted flux and current harmonics. Harmonics can be suppressed using various methods. In this paper, the harmonics are significantly reduced using Iterative Learning Control (ILC) and Neural Networks (NNs).

Triggered Repetitive Control: Application to Mechanically Ventilated Patients

IEEE Transactions on Control Systems Technology, 2023
Asymptotic rejection of a periodic disturbance can be achieved using repetitive control (RC). The aim of this article is to develop a triggered RC (TRC) framework that can handle repeating tasks that are initiated by an external disturbance induced trigger on varying intervals, which clearly violates the periodicity assumption in RC.

Predictive extended state observer-based repetitive controller for uncertain systems with input delay

Automatika, 2022
This article presents a predictive extended state observer-based repetitive controller (PESO-RC) to simultaneously track and reject periodic signals on systems with long input delay and parameter uncertainties. First, a novel extended state observer (ESO)
