modelRelay
Relay
Extends from IndustrialControlSystems.Controllers.Interfaces.BaseBlock (partial interface for a continuous time control block).
Information
Description
On-Off relay controller.
1 if u(t) >= 0
y(t) =
0 if u(t) < 0
Characteristic
If the sampling time parameter Ts is less or equal to zero, ( Ts <= 0 ) The continuous time vesion is used, otherwise the discrete time one.
