Metal hydride (MH) hydrogen storage is used in both mobile and stationary applications. MH tanks can connect directly to high-pressure electrolyzers for on-demand charging, saving compression costs. To prevent high pressure during generation needs be controlled with consideration unknown disturbances time-varying dynamics. This work presents a robust control system determine the appropriate mas...

Load frequency control (LFC) is necessary to guarantee the safe operation of power systems. Aiming at and stability problems caused by load disturbances in interconnected systems, active disturbance rejection (ADRC) was designed. There are eight parameters that need be adjusted for an ADRC, which challenging adjust manually, thus limiting development this approach industrial applications. Regar...

This paper presents an ESO-based iPI control for common rail pressure. First, a detailed mathematical model of High Pressure Common Rail Injection System (HPCRIS) is built. The mathematical model is validated by the software Matlab and commercial software AMESim. For the considered HPCRIS, an effective model free controller which is called Extended State Observer based intelligent Proportional ...

According to the serious decoupling, uncertainty, easily disturbed and nonlinear characters of the gas mixture of butterfly valve string couplets system, an ADRC static decoupling technology and the dynamic decoupling method based on extended state observer (ESO) were proposed. In this method, coupling from other input, parameters time-varying and external disturbances are all regarded as a tot...

For an electro-hydrostatic actuator (EHA), the position, speed, and current cascade three-loop control architecture are dominant in existing active disturbance rejection (ADRC). However, this suffers from many problems, such as severe noise sensitivity of extended state observer (ESO), excessive complexity structure, too tuned parameters, which makes controller not easy to implement practice. A...

Unmanned surface vehicles (USVs) have wide application prospects in military and civil fields. Motivated by the large demand for environmental protection equipment, a water-sampling USV (WS-USV) system is designed this study. The software hardware of entire are developed independently. Two water sampling modes, manual remote control mode interface automatic handling emergencies. WS-USV propelle...

Recently, assistive robots have attracted great attention from researchers in the rehabilitation field. These types of support patients to perform designated movements during a training process. Despite existence commercial systems, growing demands for improvement both hardware and control design are evident. Therefore, this paper introduces prototype pneumatic artificial muscle-based robot nam...

In order to improve the tracking ability of vehicle mounted photoelectric platform, and make its system has characteristics rapid response, small overshoot, high-precision position tracking, strong anti-interference good robustness, this paper, a joint active disturbance rejection control (ADRC) sliding mode (SMC) method is proposed, which can effectively equipment. Firstly, mathematical model ...

The electronic wedge brake system (EWB) used in the automotive industry is a new structure designed for brake-by-wire systems. This paper proposes novel EWB which mainly composed of screw-driven wedged inner pad, fixed outer caliper-flexible rotor and hybrid stepper motor. proposed does not have planetary gear set or ball screw mechanism, it simplified existing to take advantage self-interlocki...

This paper presents a novel reconfigurable control method for the planar vertical take-off and landing (PVTOL) aircraft with potential actuator failures. A cascade active disturbance rejection controller (ADRC) is used to counteract the adverse effects when the actuator failure occurs. The coordinate transformation is used for model decoupling due to the severe coupling between some variables. ...
