Relay

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.

Extends from IndustrialControlSystems.Controllers.Interfaces.BaseBlock (partial interface for a continuous time control block).

Parameters

Relay with hysteresis

Information

  

Description

On-Off relay with hysteresis controller.

            1 if u(t) >= ThH and y(t) == 0
   y(t)  = 
            0 if u(t) < ThL  and y(t) == 1
  

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.

Extends from IndustrialControlSystems.Controllers.Interfaces.BaseBlock (partial interface for a continuous time control block).
