5. Looped systems overview
Two approaches are presented in this section. The first, entitled "industrial control", applies classical automatic methods in a monovariable framework (single input, single output). The second, entitled "advanced synthesis methods", uses a multivariable state representation and relies mainly on a temporal study.
5.1 Industrial control
Here we consider the classic loop, shown in figure 21 , in which the process to be controlled is described by its input/output transmittance G(s). Its output is assumed to be subject to additive disturbances noted d(t). The measured output is y(t). The controller's output is the control signal u(t), and it has two inputs: a setpoint...
