analyze model sensitivity and tune model parameters

simulink® design optimization™ provides functions, interactive tools, and blocks for analyzing and tuning model parameters. you can determine the model’s sensitivity, fit the model to test data, and tune it to meet requirements. using techniques like monte carlo simulation and design of experiments, you can explore your design space and calculate parameter influence on model behavior.

simulink design optimization helps you increase model accuracy. you can preprocess test data, automatically estimate model parameters such as friction and aerodynamic coefficients, and validate the estimation results.

to improve system design characteristics such as response time, bandwidth, and energy consumption, you can jointly optimize physical plant parameters and algorithmic or controller gains. these parameters can be tuned to meet time-domain and frequency-domain requirements, such as overshoot and phase margin, and custom requirements.

about design optimization


  • optimize simulink models that invoke third-party simulation tools or contain legacy simulation code.


  • use parallel computing, fast restart, and accelerator simulation model to speed up parameter estimation, response optimization, and sensitivity analysis tasks.


  • when you optimize parameters of a simulink model to meet design requirements, simulink design optimization software automatically converts the requirements into a constrained optimization problem and then solves the problem using optimization techniques.

  • how the software formulates parameter estimation as an optimization problem

    estimation parameters are tuned to minimize the difference between the simulated and measured model responses.
