Robust Control and Estimation Framework for Parallel Manipulators: A Comparative Study of Super-Twisting and Fractional-Order PID Strategies
This research investigates the problem of robust control of a nonlinear, fast-dynamics, high-precision planar manipulator with a limited workspace. Starting from a mathematical model formulated in terms of Euler-Lagrange dynamics, the proposed approach considers, given the limitations of the physical system, that some...

Data-Driven Robust Servo-Regulator Trade-Off Design of Fractional-Order PID Controllers in the Frequency Domain
PID controllers are widely used in industrial applications; however, achieving a balance between robustness and control performance, particularly between servo and regulator functions, remains challenging. This paper presents a data-driven PID controller design methodology that addresses these tradeoffs in the frequenc...

Zeroing neurodynamics proportional-integral-derivative controller for order-2 system: design, analysis, and verification
This paper presents a zeroing neurodynamics proportional-integral-derivative (PID) controller for an order-2 single-input single-output (SISO) affine-in-control nonlinear system. The controller is derived from zeroing neurodynamics (ZN) and reformulates PID gains through ZN parameters, establishing an explicit correspo...

Optimal Discrete PI Controller Design for a DC-DC Boost Converter Fed PMDC Motor Drive System Using Constrained Optimization and Routh–Hurwitz Stability Analysis
In this paper, a design of an optimal discrete PI controller for a DC-DC boost converter that fed a PMDC motor drive system is presented. The small signal model (SSM) is extracted and validated theoretically and experimentally. The system transfer function has a right half plane zero (RHPZ) which adversely affects the...

Maximum Sensitivity-Based PI Controller Design for First-Order Unstable and Integrating Systems
The proposed paper focuses on introducing a simple and practical PI control approach based on the direct synthesis method for unstable first-order or integrating processes with time delay. The control scheme highlights the enhancement on set-point tracking and disturbance rejection so that good performance can be analy...
