1.2 Classification of Control System

Which type of control system uses signals that are continuous in the time domain?

• Continuous

• Non-linear

• Discrete

• Linear

What is an example of a continuous control system?

• Digital clock

• AC motor

• Temperature control in a heating system

• Microcontroller-based system

Linear control systems can be predicted using which type of equations?

• Cubic equations

• Quadratic equations

• Exponential equations

• Linear equations

What is a classic example of a linear control system?

• AC motor control

• Inverted pendulum

• DC motor control

• Robotic arm control

Non-linear control systems are more complex to analyze because:

• They have linear characteristics

• Their behavior is not easily predicted using linear equations

• Their behavior is easily predicted

• They have fewer variables

What is an example of a non-linear control system?

• AC motor

• DC motor

• Digital clock

• Microcontroller-based system

Kinetic control systems are designed to control variables like:

• Flow

• Temperature

• Pressure

• Displacement

What is a characteristic of kinetic control systems?

• Involve pneumatic manipulators

• Respond to a changing set point

• Fast response with a small delay time

• Slow response with a large delay time

Process control systems generally respond to a:

• Small delay time

• Fast response

• Changing set point

• Fixed set point

Which type of control system is used in industrial chemical processing?

• Linear control system

• Non-linear control system

• Process control system

• Kinetic control system
