In high‐speed maglev trains, the active guidance system is responsible for centring the vehicle relative to the track, a function that becomes critical under centrifugal forces, crosswinds, and track irregularities. To address the limitations of existing control methods in multi‐disturbance environments, this paper proposes a gap‐loop active ...

The compressibility of air, the uncertainty of dynamic models, and the existence of friction make pneumatic servo systems exhibit strong nonlinearity. Furthermore, the confluence of pneumatic-system nonlinearity and interference from the position system induces oscillations within the system, thereby posing a formidable challenge for achieving precise ...

Using a nine‐state islanded‐microgrid model with six heterogeneous distributed energy resources, we first establish an overlooked modelling prerequisite: the control‐to‐frequency map has relative degree two (CB = 0, CAB≠0$\text{CAB} \ne 0$), so designing the cascaded extended state observer (CESO) for relative degree one cancels the wrong dynamic term ...

Dual‐Path Control With Data‐Driven Latent Residual Modelling for Nonlinear Systems
This paper presents a unified dual‐path control framework that combines a nominal primary controller with a data‐driven latent residual model to handle nonlinearities, disturbances, delays, and parameter uncertainties. The real‐nominal mismatch is represented in latent coordinates and compensated by a secondary controller implemented as latent‐space ...

Longitudinal velocity control of autonomous driving based on extended state observer
Active Disturbance Rejection Control (ADRC) possesses robust disturbance rejection capabilities, making it well‐suited for longitudinal velocity control. However, the conventional Extended State Observer (ESO) in ADRC fails to fully exploit feedback from

To address the poor dynamic response and limited disturbance rejection of conventional dual‐loop PI control in three‐phase voltage source PWM rectifiers (VSRs), this paper proposes a composite control strategy featuring an improved sliding mode control (SMC) for the voltage outer‐loop and a back‐propagation neural network (BP‐PID) controller for the ...

This letter proposes a robust control framework based on a sliding mode control barrier function to address the strong nonlinearity and disturbances in air intake environment simulation systems. By integrating the extended state observer with sliding mode control and barrier functions, the method ensures high‐precision trajectory tracking and ...

Damping Compensation for Active Vibration Isolation System With Active Disturbance Rejection Control
The analysis of classic active disturbance rejection control (ADRC) for active vibration isolation systems (AVIS) with electromagnetic actuators demonstrates that directly applying ADRC to these systems has some shortcomings. To overcome the limitations of classic ADRC in AVIS with electromagnetic actuators, damping compensation is proposed to enhance ...
