Digital Control Systems topics include: Signal reconstruction, z transform, z-transfer function, equations, z and s domain relationship, stability analysis and compensation techniques. A digital control system (DCS) uses a computer to process signals from sensors and control a system or process. DCSs are a mix of discrete-time and continuous-time behavior. They can be in the form of a microcontroller, ASIC, or standard desktop computer.  DCSs have several advantages over other control systems, including: Improved process control: DCSs use advanced control algorithms, such as PID control,...
