- Relieves the user, design or commissioning engineer, from the tedious manual and often iterative process.
- Results in a very close to the theoretical limit of achievable performance, with very limited intervention and system knowledge.
- Speaks the language of the practical control engineer:
- Gain-margin, phase-margin, reduce sensor’s noise effects.
- Cannot miss a ‘good’ controller (transfer function), even in complex multiple feedback-sensor configurations or cascaded systems.
- Handles plant uncertainty as it is.
- g. robustness to the true plant uncertainty.
- Design for the user chosen architecture including option to fix some chosen filters values.
- Therefor enables to design scheduled controllers.
- Supplies a set of controllers sorted to a chosen criterion from which the user can chose and test.
- Does not require an analytic model of the plant.
- it can be directly applied to measured-data frequency response, as happens in many applications.
QFD SW Tool
The selection is done through observation of time-domain simulations and/or frequency domain analysis.
The QFD is suitable for industrial / machine plants, for the design of common control architectures (PD, PID, PI, Cascaded, etc.)
In order to minimize control efforts and sensor’s noise effects, it implements filters such as low-pass, notch, lead/lag; and common industrial specs such as gain and phase margins and plant uncertainty.
Quantitative Feedback Design
Mitigates any real-life system configuration or problem:
- Sensors/Data fusion
- Heat transfer
- Chemical Processes
- Vehicle dynamics
- Mechanical systems
- Motors and engines
