QFD Toolbox by Digital Feedback Technology
QFD Toolbox™ is a unique toolbox in the field of control design. Based on classical control theory it extends the scope of traditional criteria and control objectives to meet almost any possible system's closed-loop requirement with unprecedented efficiency. It can use parametric models as well as non-parametric ones (frequency response) in order to design controllers. Moreover, it can handle plant uncertainty using multiple modeling transfer functions. A wide GUI is available by which full problem statement and closed loop analyses in time and frequency domain can me executed.
