Multirate Digital Redesign of Continuous Time Controllers Based on Closed-loop Performance
نویسندگان
چکیده
This paper presents a multirate H 1 optimal digital redesign of continuous time controllers. It focuses on the performance of the closed loop system under digital control. The resulting approximation criterion is a measure for stability of the control system. The discrete time controller is obtained through minimization of this criterion , which can be performed with standard software used for H 1 controller design. A hard disk drive servo example is given to show the proposed digital redesign method.

Continuous-time controller redesign for digital implementation: A trajectory based approach
Given a continuous time nonlinear closed loop system, we investigate sampled–data feedback laws for which the trajectories of the sampled–data closed loop system converge to the continuous time trajectories with a prescribed rate of convergence as the length of the sampling interval tends to zero. We derive necessary and sufficient conditions for the existence of such sampled–data feedback laws...
متن کاملIssues in Multirate Process Control
Multirate systems are encountered when some signals of interest are sampled at a di erent rate than others. For example, in the process industry, composition measurements in distillation columns are typically sampled at a slower rate than temperatures and ow rates. In the context of closed-loop control, such multirate systems pose a challenging problem due to several reasons such as increased c...
متن کاملOn Multirate Digital Redesign of Analog Controllers
In this paper, optimal digital redesign is studied within the framework of sampled-data control theory. In particular, multirate discretization of analog controllers is considered using an H 2 or H 1 optimality criterion. Solutions are obtained via multirate H 2 or H 1 optimization with a causality constraint due to the multirate structure. In two design examples studied , comparison of the pro...
متن کاملDigital Redesign of Continuous Time Controller by Multirate Sampling and High Order Holds
This paper presents the digital redesign of continuous time controller when the measurement sampling period is relatively large and standard discretization methods are most likely not able to provide a suitable digital controller from either stability or performance point of view. An analysis tool is provided to improve the performance of digital control systems by the following two measures: 1...
متن کاملMultirate Digital Decentralized Control Design
Multirate digital decentralized control design is presented for linear timeinvariant systems with interaction between subsystems. The design technique, implemented in multirate digital control, eventually allows us to separately design controllers for each subsystem without considering interaction between them. The resulting closed-loop system with interaction between subsystems being eliminate...
