Prepr. 2nd IFAC Symp. on Robust Control Design pp. 43-48, 1997. LOW ORDER CONTROL DESIGN BY FEEDBACK RELEVANT IDENTIFICATION AND CLOSED LOOP CONTROLLER REDUCTION
نویسنده
چکیده
An approach is presented that can be used to obtain low complexity controllers for an unknown system. In this approach, the identi cation of a set of models is used to represent the incomplete knowledge of the system. Subsequently, the set is used for the synthesis of a robust controller. In order to design low complexity controllers, the aim is to nd a low complexity representation of the set. Additionally, a closed loop reduction tool can be used to decrease the controller complexity further. This approach will be illustrated by an application to a multivariable positioning mechanism present in a wafer stepper.

Design of Observer-based H∞ Controller for Robust Stabilization of Networked Systems Using Switched Lyapunov Functions
In this paper, H∞ controller is synthesized for networked systems subject to random transmission delays with known upper bound and different occurrence probabilities in the both of feedback (sensor to controller) and forward (controller to actuator) channels. A remote observer is employed to improve the performance of the system by computing non-delayed estimates of the sates. The closed-loop s...
متن کاملLeast Disturbing Closed-loop Identification Experiment for Control
This paper presents results on closed-loop identification experiment design for control. The objective is to design the least costly closed-loop identification experiment such that the controller designed with the identified model stabilizes and achieves a prescribed level of H∞ performance with the unknown true system.

متن کاملController design for a closed-loop micromachined accelerometer
This paper presents control strategies for the design of a digital closed-loop micromachined accelerometer. The microsystem is composed of a mechanical part sensitive to the external acceleration, and a fully integrated electronic part devoted to the readout and control. A feedback control approach was used from the beginning of the sensor design in order to reach a good trade-off between circu...
متن کاملCooperative Control of Multiple Quadrotors for Transporting a Common Payload
This paper investigates the problem of controlling a team of Quadrotors that cooperatively transport a common payload. The main contribution of this study is to propose a cooperative control algorithm based on a decentralized algorithm. This strategy is comprised of two main steps: the first one is calculating the basic control vectors for each Quadrotor using Moore–Penrose theory aiming at coo...
متن کاملVirtual 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...
