Robust Position Control of an Electro‐Hydraulic Actuator via Metaheuristic Optimization of a Fractional‐Order PID Controller

International Journal of Mechanical System Dynamics, EarlyView.
ABSTRACT In this study, a robust position control strategy is presented for a two‐stage electro‐hydraulic actuator system using a fractional‐order proportional–integral–derivative (FOPID) controller tuned by Kirchhoff's law algorithm (KLA). Electro‐hydraulic systems exhibit strong nonlinearities, parameter uncertainties, and external disturbances ...

From Biological Fractal Dynamics to Analog Fractional‐Order Circuits: A System Design Framework Based on Operatorization Thought

International Journal of Mechanical System Dynamics, EarlyView.
ABSTRACT Fractional calculus, with its unique advantage in describing memory and nonlocal effects, has become a key tool for modeling nonlinear dynamic systems. Its integration with circuit systems has opened up a new paradigm for modern circuit design.

Real‐Time Fractional Control of an Electrohydraulic System Using Low‐Cost Technology

International Journal of Mechanical System Dynamics, EarlyView.
ABSTRACT Advances in control methods for electrohydraulic systems (EHS) improve performance by addressing nonlinearities and unknown parameters, although most studies are limited to numerical simulations. Furthermore, research with experimental validation often relies on high‐performance computing equipment, specialized data acquisition cards, and ...

Dynamic Performance Enhancement of a High‐Agility Hypersonic Mechanical System via a Learning‐Augmented Robust Control Architecture

International Journal of Mechanical System Dynamics, EarlyView.
ABSTRACT The design of control systems for high‐agility mechanical systems operating in extreme environments is a significant challenge in nonlinear dynamics. This paper addresses the complex dynamic control problem of a hypersonic interceptor, modeled as a multi‐input multi‐output (MIMO) mechanical system characterized by strong aerodynamic cross ...

Designing ZV and ZVD Input Shapers Using the Designed Fixed Output Response Method to Suppress Residual Vibration of Overhead Crane Systems With Trolley Traveling and Payload Hoisting

International Journal of Mechanical System Dynamics, EarlyView.
ABSTRACT Classical Zero Vibration (ZV) and Zero Vibration and Derivative (ZVD) input shapers are designed around a fixed nominal natural frequency and cannot accommodate the time‐varying dynamics introduced when an overhead crane simultaneously travels and hoists a payload.
