Set Point and Identifiability in the Closed Loop with a Minimum-variance Controller
نویسنده
چکیده
The meaning of nonzero set points for the identiiability of the AR-MAX model parameters in a closed-loop system with a minimum-variance controller is explained and discussed. It is pointed out that, in the case of a zero set point and an ARMAX model resulting from the discretization of a continuous-time plant, the model parameters cannot be identiied in a closed-loop system with a minimum-variance controller. It is also shown that in the case of appropriately varying set point or the existence of a delay in the plant, the identiiability conditions of the parameters can be fulllled.

A New Near Optimal High Gain Controller For The Non-Minimum Phase Affine Nonlinear Systems
In this paper, a new analytical method to find a near-optimal high gain controller for the non-minimum phase affine nonlinear systems is introduced. This controller is derived based on the closed form solution of the Hamilton-Jacobi-Bellman (HJB) equation associated with the cheap control problem. This methodology employs an algebraic equation with parametric coefficients for the systems with s...
