On Stable Full-order and Reduced-order Lqg Controllers
نویسندگان
چکیده
The problem of deriving a suboptimal LQG controller which is internally stable is considered. In the case where the controller is internally unstable a procedure is given for modifying the optimization parameters, i.e. the state weighting matrix and/or the process noise intensity. Sufficient conditions for controller stability of appropriately modified optimization problems are given for both the full-order and reduced-order cases. A final tuning procedure is then used to minimize the deviation from the original LQG problem.

Near-Optimal Controls of a Fuel Cell Coupled with Reformer using Singular Perturbation methods
A singularly perturbed model is proposed for a system comprised of a PEM Fuel Cell(PEM-FC) with Natural Gas Hydrogen Reformer (NG-HR). This eighteenth order system is decomposedinto slow and fast lower order subsystems using singular perturbation techniques that provides tools forseparation and order reduction. Then, three different types of controllers, namely an optimal full-order,a near-opti...
متن کاملController reduction via stable factorization and balancing
A controller reduction procedure based on a representation of a controller as a matrix function defined using stable proper transfer functions and employing a balancing technique is studied in this paper. For a certain right coprime factorization of an LQG designed controller K(s) = N(s)D-'(s), we approximate using a balancing technique the pair [D(s), N(s)lT by a low-order pair [D,(s), N,(s)lT...
متن کاملThe Optimal Projection Equations for Fixed - Order Dynamic Compensation
First-order necessary conditions for quadratically optimal, steady-state, fixed-order dynamic compensation of a linear, time-invariant plant in the presence of disturbance and observation noise are derived in a new and highly simplified form. In contrast to the pair of matrix Riccati equations for the full-order LQG case, the optimal steady-state fixed-order dynamic compensator is characterized...
متن کاملLQG-Balanced Truncation Low-Order Controller for Stabilization of Laminar Flows
Recent theoretical and simulation results have shown that Riccati based feedback can stabilize flows at moderate Reynolds numbers. We extend this established control setup by the method of LQG-balanced truncation. In view of practical implementation, we introduce a controller that bases only on outputs rather than on the full state of the system. Also, we provide a very low dimensional observer...
متن کاملPerformance Preserving Frequency-Weighted Controller Reduction with Exact Solution for Low-Order Weights
In this paper, a new H∞ performance preserving frequency-weighted controller order reduction with exact solution for low-order weights is proposed. Given a stabilizing controller that must be stable and satisfy an H∞ performance bound on the closed-loop systems, we derive a sufficient condition for reduced-order controllers to be stabilizing and satisfy the same performance bound, i.e., approxi...
