Final answer:
A controllable system has minimal couplings and strategic actuator location. An example of a controllable system is a car.
Step-by-step explanation:
In order for a system to be controllable, it needs to have certain characteristics. These characteristics include minimal couplings and strategic actuator location. Minimal couplings mean that the system should have as few interconnections between its components as possible, reducing the complexity of the system. Strategic actuator location means that the actuators, which are devices responsible for controlling the system, should be strategically placed in order to have maximum control over the system.
As an example, consider a car. The car's system consists of various components such as the engine, steering, brakes, and accelerator. In order for the car to be controllable, it is important for the couplings between these components to be minimal, meaning that they should operate independently of each other. Additionally, the location of the actuators, such as the pedals and steering wheel, is strategically placed to allow the driver to have maximum control over the car.
