Linear control of a boiler–turbine unit: Analysis and design

Modified active disturbance rejection control for time-delay systems

“…The fuel dynamics of a boiler turbine unit is modeled as a FOPTD system in [30] with the following transfer function,…”

A cyber-physical experimentation environment for the security analysis of networked industrial control systems

“…The process runs at a typical operating point [23] with the value of the fuel valve set to 0.34, the value of the steam valve set to 0.69 and the value of the feed water valve set to 0.433. The Emulab NS script from Figure 11 shows that nodes and network connections are configured easily with typical NS commands.…”

Pressure equilibrium control for boiler-turbine units

“…Just as discussed in Section I, various control theories and techniques can be used to design a decoupling controller for this model. The adopted method which based on linear and multivariable theory is from [2]. After identifying and deducing, the final form of the controller is expressed as: μ (6) where N E is the error between N R and N. combining the controller with the 500MW model, a multivariable decoupling control system will be established as Fig.…”

“…The controller is of PID type, and thus is easy to be implemented. [2] analyzed the dynamic characters of a 330MW boiler-turbine unit in Inner Mongolia, China, and adopted the method proposed in [1] to construct the field controller. [3] deduced a feedback linearization law via the dynamic extension algorithm of vector relative degree for a typical boiler-turbine unit model to overcome the influence of process nonlinearities and improving the load-following capability.…”
