Sampled update and hold
Understand the `Sampled update and hold` governing equation when choosing an objective optimization for Control Systems.
This relationship describes part of the physical problem being optimized:
\mathbf x_k=\mathcal F(\mathbf x_{k-1},\mathbf u_k)\ \text{at events},\quad\mathbf x_k=\mathbf x_{k-1}\ \text{otherwise}
Check the variables, signs and units against your intended model. The objective and constraints must use quantities available in the selected study; this equation page does not create a separate editable model feature.
