Limit-cycles prevention via multiple H∞ constraints with an application to anti-windup design
نویسنده
چکیده
Rate and magnitude control limitations are often responsible for the apparition of undesired limit-cycles in the resulting nonlinear closed-loop system. Based on the wellknown describing function approach, it is shown in this paper that such limit cycles can be avoided as soon as H∞ constraints are simultaneously satisfied by appropriately chosen linear interconnections. This result is then used to design anti-windup compensators.

Robust Anti-Windup Control Considering Multiple Design Objectives
A new saturation control technique is proposed to design multiobjective and robust anti-windup controllers for linear systems with input saturations. Based on the characterization of saturation nonlinearities and modeling uncertainties via integral quadratic constraints IQCs , this method considers a mixed H2/H∞ performance indexes while maintaining dynamic constraints on the controller. The an...
متن کاملRobust Anti-Windup Control Design for PID Controllers–Theory and Experimental Verification
This paper addresses an approximation-based anti-windup (AW) control strategy for suppressing the windup effect caused by actuator saturation nonlinearity in proportional–integral–derivative (PID) controlled systems. The effect of actuator constraint is firstly regarded as a disturbance imported to the PID controller. The external disturbance can then be modeled by a linear differential equatio...

متن کاملLmi-based Synthesis of Anti-windup Filters with Pole Constraints
This paper presents a design method for a linear anti-windup filter with filter pole constraints. The anti-windup design problem can be cast as an LMI optimization problem. The anti-windup filter is optimized for L2 performance while its poles are constrained in a predefined region. The constrained poles ensure the fast recovery of saturation free linear responses and practical implementation o...
متن کاملAN H-inf DYNAMIC ANTI-WINDUP SCHEME FOR INPUT-CONSTRAINED LINEAR SYSTEMS
This paper proposes a dynamic compensation scheme for inputconstrained linear systems to cope with the windup phenomenon. Given a linear controller for such a linear system designed without considering its input constraints, an additional dynamic compensator is proposed to account for the constraints. This dynamic anti-windup scheme is based on H∞ optimization, and some stability properties of ...
