Note that we still only have one control valve. Instead of manipulating steam valve directly for temperature control, the valve is now controlling the flow of the steam to the process from PID 2. The ...

Figure 2: Steam heater controlling the critical temperature of a process fluid flow (W), using feedforward-corrected cascade control. A1: The main advantage of cascade control is that disturbances ...

One important factor in power plant control system performance is the response time of the process measurement used in the control system. The response time of boiler steam temperature sensors and ...

Impact on Control Loop Performance. The February 2011 article on this topic explained how a simple simulation was done to evaluate the effect of a faster temperature response on the performance of ...

A temperature process is master control and a steam flow process is slave control have become so integrated. This paper used the velocity form algorithm in PID to optimize the values and design a ...
