Nonlinear Dynamic Model-Based Adaptive Control of a Solenoid-Valve System
Journal of Control Science and Engineering, 2012 In this paper, a nonlinear model-based adaptive control approach is proposed for a solenoid-valve system. The challenge is that solenoids and butterfly valves have uncertainties in multiple parameters in the nonlinear model; various kinds of physical ...

Optimal control of nonlinear systems: a predictive control approach [PDF]
, 2003 A new nonlinear predictive control law for a class of multivariable nonlinear systems is presented in this paper. It is shown that the closed-loop dynamics under this nonlinear predictive controller explicitly depend on design parameters (prediction time
