6. Analyze System Responses in Transient and Steady-State Conditions
This chapter covers the analysis of system responses in control systems, outlining both transient and steady-state behaviors. Understanding these responses is crucial for designing stable and high-performance systems. Key aspects include parameters affecting transient response, steady-state error, and the use of time and frequency domain analysis methods.

What we have learnt
- The transient response includes rise time, overshoot, settling time, and damping effects.
- The steady-state response reflects the system’s accuracy and error characteristics, which can be quantified using error constants.
- Both responses are critical for evaluating and designing control systems.
Key Concepts
- -- Transient Response
- The behavior of a system immediately after a change in input before it reaches a steady-state.
- -- SteadyState Response
- The behavior of the system after it has settled and transient effects have subsided.
- -- Rise Time
- The time it takes for the output to rise from 10% to 90% of its final value.
- -- Settling Time
- The time required for the output to remain within a certain percentage of its final value.
- -- Damping Ratio
- A dimensionless measure that describes the amount of damping in the system influencing its speed and oscillation.
- -- SteadyState Error
- The difference between the desired output and the actual output as time approaches infinity.
