Full text download:http://tecdat.cn/?p=22319 This article establishes a Partial Least Squares (PLS) regression (PLSR) model and evaluates its predictive performance. To create a reliable model, we also implement several common outlier detection and variable selection methods to remove potential outliers and use a subset of selected variables to “clean” your data(Click the “Read the original text” … Read more

Although MathWorks officially only lists support for Ubuntu 24.04 LTS, 22.04 LTS, and earlier versions in the system requirements for R2025a (not mentioning Ubuntu 25.04). However, in a practical environment, I successfully completed the installation and running tests of MATLAB R2025a on Ubuntu 25.04 without encountering compatibility or dependency issues, indicating that this version is … Read more
1. Introduction to PID Control The PID (Proportional-Integral-Derivative) controller is the most classic feedback control algorithm in industrial control. It generates the control quantity through a linear combination of the proportional (Proportional), integral (Integral), and derivative (Derivative) parts of the error signal, achieving precise control of the system. Mathematical Model of PID Controller: 2. Case … Read more
The following is a MATLAB-based simulation example of a Fractional Order PID (FOPID) control, utilizing MATLAB’s Simulink tool and the FOMCON toolbox: System Model Assume the controlled object is a first-order inertia link with pure delay (FOPDT) model: Where, , , . Fractional Order PID Controller Design The form of the fractional order PID controller … Read more

The Transient Trigonometric Harris Hawks Optimizer (TTHHO) is a hybrid optimization algorithm inspired by the Transient Search Optimizer (TSO) and the Harris Hawks Optimizer. This algorithm intelligently explores the search space and adaptively optimizes the positions of grid nodes while considering various constraints and objectives. It integrates the advantages of HHO, SCA, and TSO, aiming … Read more
The fi function supports six rounding modes, which can be observed through the code snippets shown in the following three images. The input data x is a double-precision floating-point number, and it is to be converted into a fixed-point number with a sign bit of 1, a word length of 4, and a fractional length … Read more
The dynamic response of a Single Degree of Freedom (SDOF) system under earthquake effects based on Matlab. The displacement, velocity, and acceleration responses of the structure are calculated using two numerical integration methods (central difference method and Newmark method), and the results of these two methods are compared. Earthquake acceleration time history data is imported. … Read more
