This site collects research notes on how the golf swing works. It also covers related topics in multibody dynamics and control theory.
My name is Dieter Olson. I am a chemical engineer by training, and I work in industrial research and development. This is a personal biography. It is not independent evidence for the scientific claims on this site.
I have long been interested in the science of the golf swing. I also like to apply engineering to biomechanics. I read the golf biomechanics literature, including key work by Cochran & Stobbs (1968), Jorgensen (1970), and Nesbit (2005). I also read control theory texts by Isidori, Tedrake, and Murray et al. That led me to apply nonlinear control theory and multibody dynamics to understand the swing in more depth. See the Bibliography for the full reference list.
My research interests include robot control, multibody modeling, and parallel mechanisms. I am also interested in how passive dynamics interact with active control—the namesake of this website. The central question is this: how much of an observed motion comes from the system's own dynamics (drift), and how much comes from active muscle input (control)?
Scope: AffineDrift publishes analysis that depends on its models, along with editorial synthesis. A model's split into drift and input does not uniquely identify muscle forces, neural intent, coaching advice, or clinical effect. Reading it that way would need additional measurements and validation.
