Minimize Fuel with ODE Optimization

An optimization solution demonstrates how to minimize the integral of the acceleration. Initial and final conditions are specified for the position and velocity. An upper bound on position is also given.

A very good lesson. Please continue

Could such a technique be used for model updating?
Lets say you have a mass spring system of which you do not exactly know the properties (i.e. stiffness, damping, mass) but you do have accurate measurements of the oscillations over time and in the frequency domain. Could the properties of the system be derived using an analysis like this?

Yes, it is also built for parameter regression. Here is a recent StackOverflow question that is related: stackoverflow.com/questions/75801763/gekko-optimization-with-a-sinusoidal-load-on-a-mass-spring-system
