Study Notes
Static Characteristics of Mechatronics System
Linearity
- Definition: The ability of a system to respond proportionally to changes in input
- Characteristics:
- Ideal linear system: output directly proportional to input
- Real-world systems: non-ideal, but approximated as linear within a certain range
- Linearity is important for system analysis and design
Sensitivity
- Definition: The ratio of change in output to change in input
- Characteristics:
- Measures how much the output changes in response to a unit change in input
- High sensitivity: small input changes result in large output changes
- Low sensitivity: large input changes result in small output changes
- Importance: crucial in system design for amplification or attenuation of signals
Accuracy
- Definition: The closeness of the system's output to its true value
- Characteristics:
- Measures how close the system's output is to the actual value
- High accuracy: system output is very close to true value
- Low accuracy: system output is far from true value
- Importance: critical in applications where precise measurements are required
Repeatability
- Definition: The ability of a system to produce the same output for repeated inputs
- Characteristics:
- Measures how consistent the system's output is for identical inputs
- High repeatability: system produces same output for repeated inputs
- Low repeatability: system produces varying outputs for repeated inputs
- Importance: essential in applications where consistent results are required
Stability
- Definition: The ability of a system to return to its equilibrium state after a disturbance
- Characteristics:
- Measures how well the system resists changes to its output
- Stable system: returns to equilibrium state after a disturbance
- Unstable system: output diverges or oscillates after a disturbance
- Importance: critical in applications where system stability is essential for safety and performance
Static Characteristics of Mechatronics System
Linearity
- A system is considered linear if its output responds proportionally to changes in input
- Ideal linear systems have outputs directly proportional to inputs

Sensitivity
- Sensitivity is the ratio of change in output to change in input
- It measures how much the output changes in response to a unit change in input
- High sensitivity means small input changes result in large output changes
- Low sensitivity means large input changes result in small output changes
- Sensitivity is critical in system design for amplification or attenuation of signals
