Design of Optimal Low-Order Feedforward Controllers
نویسندگان
چکیده
Design rules for optimal feedforward controllers with lead-lag structure in the presence of measurable disturbances are presented. The design rules are based on stable firstorder models with time delays, FOTD, and are optimal in the sense of minimizing the integratedsquared error. The rules are derived for an open-loop setting, considering a step disturbance. This paper also discusses a general feedforward structure, which enables decoupling in the design of feedback and feedforward controllers, and justifies the open-loop setting.

Design of Low-Order Controllers using Optimization Techniques
In many applications, especially in the process industry, low-level controllers are the workhorses of the automated production lines. The aim of this study has been to provide simple tuning procedures, either optimization-based methods or tuning rules, for design of low-order controllers. The first part of this thesis deals with PID tuning. Design methods for both SISO and MIMO PID controllers ...

In this paper, existence and solution of the feedforward plus feedback control law for model reference control of a class of second-order dynamic systems are investigated. A necessary and sufficient condition for the existence of the controllers is established. Based on a result of parametric eigenstructure assignment in second-order dynamic systems, general complete parametric expressions for ...

متن کاملSimultaneous Design and Control of Polymerization Reactors
Abstract: Chemical engineering science has recognized the necessity of integrating process design and control; however, few steps have been taken in this direction in polymer science. In this work, a Mixed-Integer Dynamic Optimization approach is used for the simultaneous design and control of a styrene polymerization reactor. Our goal is to design the process and its control system in order to...
