RISNonlinear Compensation and Stochastic Control
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: The usual ARMAX linear model for a discrete-time system is generalized to include a nonlinear characteristic. A nonlinear compensation scheme is proposed which enables a modified LQG control ...
Long Range Predictive Optimal Control Law With Guaranteed Stability for Process Control Applications
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: The Generalized Predictive Control law has been successfully applied in industrial applications but has limitations on nonminimum phase processes for some of the most obvious choices of cost-functions. ...
State-Space Approach to LQG Multivariable Predictive and Feedforward Optimal Control
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Two extensions of the LQG optimal control problem are presented which enable prediction and feedforward action to be introduced in a state equation framework. Predictive control is first considered ...
Multichannel Optimal Linear Deconvolution Filters and Strip Thickness Estimation From Gauge Measurements
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: A solution is presented to the H2 optimal deconvolution filtering, smoothing and prediction problems for multivariable, discrete, linear signal processing problems. A weighted H2 cost-function is ...
Polynomial Solution of Predictive Optimal Control Problems For Systems in State-Equation Form
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: The solution of linear quadratic predictive optimal control problems for systems represented in state-equation form, but using a polynomial systems approach, is considered. A multistep cost-function ...
H∞ Controllers With a PID Structure
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: A review is given of the new H∞ Observations Weighted (HOW) optimal control law. The conditions under which the H∞ controller has a PID structure are identified and some implications for PID ...
3 1/2 DOF Polynomial Solution of the Inferential H2/H∞ Control Problem With Application to Metal Rolling
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: The solution of a new inferential 3 1/2-degree-of-freedom stochastic optimal control problem is discussed which may be either H2 or H∞ optimal. The system includes a 2 1/2-degree-of-freedom ...
H∞ Observations Weighted Control Law
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: A H∞ optimal control problem is considered which leads to a particularly simple controller structure. The expression for the optimal controller only requires the solution of one diophantine ...
Design of a Multivariable Neural Controller and Its Application to Gas Turbines
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: The algorithm for a multivariable controller using neural network is based on a discrete-time fixed controller and the neural network provides a compensation signal to suppress the nonlinearity. ...
Solution of Finite-Time LQP Optimal Control Problems for Discrete-Time Systems
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: The deterministic discrete-time optimal control problem for a finite optimization interval is considered. A solution is obtained in the z-domain by embedding the problem within a equivalent ...
