Control System Types and Orders

This lecture on control systems covers the definition and types of systems, focusing on the number of poles at the origin in open loop transfer functions. It explains type 0, type 1, and type 2 systems with examples, and discusses how to determine the type and order of a system using transfer functions. The lecture concludes with practical examples to reinforce the concepts.

What is the definition of the type of a system in control systems?

• The number of inputs to the system

• The number of feedback loops

• The number of poles at the origin

• The number of zeros at the origin

In a Type 0 system, how many poles are present at the origin?

• Three

• One

• None

• Two

Which of the following is true for a Type 1 system?

• It has one pole at the origin

• It has no poles at the origin

• It has three poles at the origin

• It has two poles at the origin

What characterizes a Type 2 system?

• No poles at the origin

• One pole at the origin

• Three poles at the origin

• Two poles at the origin

How is the order of a system determined?

• By the number of feedback loops

• By the number of poles at the origin

• By the number of zeros at the origin

• By the highest power of s in the transfer function
