Sliding Mode Control with Feedforward Compensation for a Soft Manipulator That Considers Environment Contact Constraints

Journal of Marine Science and Engineering, 2023
Soft manipulators have desirable environmental compatibility because of their pliability. However, this pliability also brings challenges to modeling and control when considering contact or collision with the environment. In previous work, we established

An improved capacitor voltage full feedforward control strategy for LCL‐type grid‐connected inverter based on control delay compensation

IET Power Electronics, 2021
For the LCL‐type grid‐connected inverter, when the capacitor voltage feedforward is applied, the delay in the digital control system could change the phase characteristics of capacitor voltage feedback and affect the stability of the system. To solve the

A Self-Tuning Feedforward Compensator

IFAC Proceedings Volumes, 1991
Abstract In this paper, the development of a self-tuning feedforward compensator is discussed. The technique is to witness the uncompensated load response and identify the system transfer functions from it and set the compensator for ideal compensation. The compensator is then tuned by a trial and error method so as to account for the modelling error.

Delay-Compound-Compensation Control for Photoelectric Tracking System Based on Improved Smith Predictor Scheme

IEEE Photonics Journal, 2022
High control bandwidth is usually restricted in a photoelectric tracking system (PTS) based on a Charge-Couple Device(CCD) with time delay, which hinders a good tracking performance.
