Continuoustime systems are represented by linear differential equations, while the digital systems are described by difference equations. High order terms in a difference equation are delayed copies of the signals, while high order terms in the differential equations are derivatives of the analog signal. Analysis of digital control systems textbook download. While most key features of control engineering are the same for continuous and digital control, some unique features of digital control should be considered. An introduction to digital control systems lecture. Control systems by katsuhiko ogata a fantastic book. Then you can start reading kindle books on your smartphone, tablet, or computer no kindle device required. The difference between the continuous and digital systems is that the digital system operates on samples of the sensed plant rather than the continuous signal and that the control provided by the digital controller ds must be generated by algebraic equations.
