Add a Full State-Space Feedback Controller to a Control System Model
Get a brief overview of full state feedback, learn how to use the State-Space Controller add-in, and get a demonstration of implementing the add-in using a mass-spring-damper system example.
Happy Birthday, Joseph Fourier
From heat conduction and the Fourier series to the greenhouse effect and Fourier transform, Joseph Fourier’s research has many implications in the modern world.
Combining Adaptive Mesh Refinement with Data Filtering
In a follow-up to our previous blog post on data filtering, we demonstrate how to implement adaptive mesh refinement and a Helmholtz filter for a thermal model with a nonuniform heat load.
Using Data Filtering to Improve Model Performance
Want to include experimental data in your model as a load or boundary condition, but the data varies over space or time and is noisy? Try implementing data filtering, such as a Helmholtz filter.
How to Model a Hall Effect Sensor with COMSOL Multiphysics®
Basic working principle of a Hall effect sensor: A nearby magnetic field deflects the path of current through a semiconductive sensor, which causes a measurable change in potential.
Which Radiation Interface Should I Use for My Heat Transfer Model?
Compared to the mechanisms of heat transfer by conduction and convection, heat transfer by radiation has unique characteristics. How should you account for radiation in your heat transfer models?
A Quiet Revolution: Analyzing Electric Motor Noise via Simulation
The sound we hear from electric-powered machines is a multiphysics phenomenon: A motor’s electromagnetic activity sends vibrations through both the machine and the surrounding air.
Analyzing HIFU Propagation Through a Tissue Phantom
High-intensity focused ultrasound (HIFU) is used for surgery, cancer therapy, shock wave lithotripsy, and more. Learn about how simulation can be used to analyze this noninvasive technique.
