Control
Embedded systems, sensors, actuators and feedback loops — the smallest HL topic, but questions are consistently scenario-based, so a textbook-correct answer that ignores the specific sensor/actuator given in the stem loses the context marks.
7.1 Control
- Discuss a range of control systems.
- Outline the uses of microprocessors and sensor input in control systems.
- Evaluate different input devices for the collection of data in specified situations.
- Explain the relationship between a sensor, the processor and an output transducer.
- Describe the role of feedback in a control system.
- Discuss the social impacts and ethical considerations associated with the use of embedded systems.
- Compare a centrally controlled system with a distributed system.
- Outline the role of autonomous agents acting within a larger system.
