Control Disturbances Disturbance Definition
Change in Setpoint The setpoint is the desired value of the measured variable. Its value establishes the level of energy flow in steady state conditions.Any change in its setting will require a completely new energy picture. For instance, a higher temperature for the product out will require the control system to provide a higher rate of fuel flow.Change in Supply This is a variation in any of the energy inputs to the process. A variation in the supply pressure of the fuel, for instance, or a variation in thetemperature of the raw materials, would be supply changes.Change in Demand This is a disturbance in the output flow of energy.The most common source of such a disturbance is a change in the production rate itself. If the front office asks for more output and theproduction rate is increased, the energy would certainly have to be increased.Environmental Changes Ambient temperature or atmospheric pressurealso affect the energy balance. If the equipment is outdoors, the wind velocity and direction may also play a part in altering these energy requirements.
