Many real time processes have complex, uncertain and nonlinear dynamics. Boilers are nonlinear, time varying, multi-input multi-output (MIMO) systems, whose states generally vary with operating conditions. The major problem in controlling that system is that its drum water pressure and steam flow dynamics include an integrator that results a critically stable behavior. Conventional controller p...

Abstract We present a new proof of the turnpike property for nonlinear optimal control problems, when running target is steady control-state pair underlying system. Our strategy combines construction quasi-turnpike controls via controllability, and bootstrap argument, does not rely on analyzing optimality system or linearization techniques. This in turn allows us to address several problems fin...
