Tustin

Tustin is a method used in control systems to convert continuous-time (analogue) signals into discrete-time (digital) signals, which are processed by digital controllers or computers. It approximates the behavior of a continuous system by sampling its output at regular intervals and updating the control input accordingly. This approach helps in designing digital controllers that ensure stability and accuracy when managing real-world systems like robots or industrial equipment. Tustin's method is favored because it provides a good balance between simplicity and accuracy, effectively handling the system's dynamics during the digital approximation process.
