This submission was created by Valery Tchkalov and Steve Miller to help engineers understand parameterization of hydraulic valves. The included white paper, simulation models, and MATLAB scripts cover the structure of a valve model, examples of how to use optimization algorithms to tune your valve parameters so that your simulations match characteristics on manufacturer’s data sheets, and how to use experimental data to determine realistic parameter values. The power stage and control device of valves are discussed, and the models include steady-state, transient response, and frequency domain examples.
Please read the README.txt file to get started.
For an explanation of valve modeling and several of the examples contained in this submission, please watch, “Hydraulic Valve Parameters From Data Sheets and Measured Data“
