You choose a sampling period ( T ). Kuo teaches the rule of thumb: ( T = \frac110 \times \textclosed-loop bandwidth ).
Digital control systems run the devices you use every day: smartphones sampling sensors, robots tracking positions, and industrial plants maintaining temperatures. Benjamin Kuo’s Digital Control Systems translates continuous-time intuition into discrete-time, implementable controllers—making the leap from differential equations to difference equations and on to real microcontrollers. If you want to design controllers that run on real hardware, Kuo shows you how.
To analyze a system with both digital and analog components (a hybrid system), one must derive the Pulse Transfer Function.
Consider a standard loop where a digital controller $D(z)$ controls a continuous plant $G(s)$ through a Zero-Order Hold (ZOH). The ZOH acts as a data reconstruction filter, holding the output constant between samples.
The discrete equivalent of the plant, denoted as $G(z)$, is derived by combining the ZOH and the plant transfer function: $$ G(z) = \mathcalZ \left \frac1-e^-Tss G(s) \right $$
Kuo provides extensive tables and methods for performing this transformation, which allows the engineer to treat the continuous plant as a purely discrete element within the control loop.
Benjamin Kuo’s Digital Control Systems remains a solid foundation for learning how to analyze and design digital controllers. Using a PDF copy responsibly as a study aid—paired with hands-on simulation and coding—will give you the theoretical grounding and practical skills to design sampled-data control systems.
