Control systems
- At the core of the internet of Things is a network of small(or not so small) computers with the ability to perceive and control elements of the world.
- All examples will have some common characteristics, namely:
- They can perceive on ore more aspects of the world; i.e. they can hear, see, feel, smell or taste something.
- They can produce an action in the world; i.e. they can move, turn on, or activate something
- They have a bit of “intelligence“, that uses sensed information to make decisions about when and how to produce an action.
- All these examples can be described with the following diagram:
- open-loop control system
- closed-loop control system: which make decisions based on current information AND the effect their last action hand on the world(feedback) such as the air conditioner.
