PID controller#

The PID controller block implements mathematical model of controller consisting of proportional, integrating and differentiating links (1):

(1)#\[ W(s)=K_{p}+\frac{K_{i}}{s}+K_{d}\cdot s \]

The corresponding coefficient of each link is specified in block properties. Also, the block implements limitation of the signal output from the integrating link.

By signal > 0 sent to the Integrator reset port, the integral value calculated by the integrator is equal to 0.
