2. Model interfaces with control laws
Before creating the control laws for a system, it is necessary to model the sensors and the acquisition system used by the embedded software control law, as well as the actuator control system and the actuators themselves.
2.1 Modeling sensors
Sensors measure a physical quantity by converting it into an electrical signal. This conversion is carried out with a certain uncertainty (error, measurement noise, hysteresis...) and a certain delay (called the sensor response time). Sensor characteristics are specified by the manufacturer. It should be noted that the choice of sensors will have a major influence on the performance of the control system.
The electrical signal from the sensor is processed by the acquisition system. The latter will also introduce a delay and an error in the...
