The MathWorks today announced major upgrades to three of its control design software products — Control System Toolbox 7, Simulink Control Design 2, and Simulink Response Optimization 3. The new versions provide a stronger integration with Simulink to create a streamlined platform for control design and optimization using Model-Based Design. A new graphical user interface (GUI) unifies the three products, enabling control engineers of all experience levels to now tune and optimize control systems on multidomain plant models directly in Simulink. Control System Toolbox 7, Simulink Control Design 2, and Simulink Response Optimization 3 are available now with prices starting at US$1,000 for each product.
