ADAPTIVE SUBOPTIMAL CONTROL OF INPUT CONSTRAINED PLANTS
Abstract. This paper deals with adaptive regulation of a discrete-time linear time-invariant plant witharbitrary bounded disturbances whose control input is constrained to lie within certain limits. The adaptivecontrol algorithm exploits the one-step-ahead control strategy and the gradient projection type estimationprocedure using the modified dead zone. The convergence property of the estimation algorithm is shown tobe ensured. The sufficient conditions guaranteeing the global asymptotical stability and simultaneously thesuboptimality of the closed-loop systems are derived. Numerical examples and simulations are presented tosupport the theoretical results

Learning-Based Adaptive Control for Stochastic Linear Systems with Input Constraints
We propose a certainty-equivalence scheme for adaptive control of scalar
linear systems subject to additive, i.i.d. Gaussian disturbances and bounded
control input constraints, without requiring prior knowledge of the bounds of
the system parameters, nor the control direction. Assuming that the system is
at-worst marginally stable, mean square boundedness of the closed-loop system
states is proven. Lastly, numerical examples are presented to illustrate our
results.Comment: 16 pages, 2 figures, submitted to IEEE Control Systems Letter
