Direct controller order reduction by identification in closed loop

The paper 1 addresses the problem of directly estimating the parameters of a reduced order digital controller using a closed loop type identification algorithm. The algorithm minimizes the closed loop plant input error between the nominal closed loop system and the closed loop system using the reduced order controller. It is assumed that a plant model (if necessary validated in closed loop with...

A Uniied Approach to Closed-loop Plant I D E N Tiication and Direct Controller Reduction

Closed loop output error identi cation algorithms and recently developed algorithm for direct closed loop estimation of reduced order controllers [3, 5] despite their diversity have in fact a unifying basic ground which will be enhanced. The paper also will explore the interaction between closed loop plant model identi cation and direct estimation in closed loop of reduced order controllers. Th...

Closed-Loop Controller Design

Closed-loop controllers use outputs of the system to improve overall stability and increase tolerance against external disturbances. The latter makes it possible to control inherently unstable systems. As expected, there are some important differences from open-loop controllers. Most importantly, we must distinguish between measurable outputs of the system and the properties we really want to c...

Effect of Varying Controller Parameters in Closed-Loop Subspace Identification

It is well known that subspace identification methods that assume open loop data without correlations between the input and noise, may give biased estimates when applied to closed loop data. The effect of the controller gain parameters on the quality of the identified model is studied when closed loop data are used. Several subspace identification methods (both open loop and closed loop methods...

Virtual Closed Loop Identification: A New Method for Low-Order ∞ H Controller Design

A new algorithm for H ∞ controller order reduction based on virtual closed loop identification is proposed. A high order H ∞ controller is implemented in a closed loop system simulation. Subsequently, two sets of input/output data of high order controller in closed loop operation will be attained. By selecting an appropriate filter, these data will be filtered. Afterwards, a low order controlle...
