Q. Show Advantage of digital control system over analog system?

Sampled data and digital control offer several advantages over analog systems:

• More compact and lightweight

• Improved sensitivity

• Better reliability, speed, and accuracy

• More flexibility and versatility (in programming)

• Lower cost

• More rugged in construction

• No drift

• Less effect due to noise and disturbance.

Many physical systems have inherent sampling, and hence their behavior can be described by sampled data or digitalmodels. Even the dynamics of the social, economic, and biological systems can be modeled by sampled-data system models.
