A quantitative tuning rule for input modified active disturbance rejection control is derived based on the Nyquist asymptote and desired maximum sensitivity constraint. The rule simplifies parameter tuning to a single variable and shows superior performance in superheater steam temperature system with broad industrial applicability.

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 ...

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 ...

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 ...

To improve the slip rate control effect for different road conditions during emergency braking of wheel hub motor vehicles, as well as to address the problems of uncertainty and nonlinearity of the system when the electro-mechanical braking system is used as the actuator of the ABS, a hierarchical control strategy of the anti-lock braking system (ABS ...
