Simulink Design Optimization

Overview

Simulink Design Optimization™ provides interactive tools, functions, and Simulink^® blocks for estimating and tuning Simulink model parameters using numerical optimization. An interactive tool lets you automatically estimate model parameters such as friction and aerodynamic coefficients from test data to increase model accuracy. You can preprocess test data, select model parameters to estimate, start an optimization, and validate estimation results.

You can also automatically tune design parameters in a Simulink model to meet objectives such as improved system performance and minimized energy consumption. Using design optimization techniques, you can meet both time-domain and frequency-domain constraints such as overshoot and phase margin. You can also jointly optimize physical plant parameters and algorithmic or controller gains to maximize overall system performance.

Key Features

• Model parameter estimation from test data
• Simultaneous optimization of time-domain and frequency-domain responses of Simulink models (with Simulink Control Design™)
• Graphical specification of response requirements and visual monitoring of the optimization progress
• Optimization of parameters to meet requirements specified by Model Verification blocks
• Custom constraints and cost functions for response optimization
• Scripting interface for programmatic specification of design optimization problems
• Robust design optimization, accounting for parameter variation or uncertainty

You can assess the results of the estimation by comparing plots of measured versus simulated data before the estimation (bottom left) and after the estimation (bottom right).
