Low-Gain Integral Control for Multi-Input Multioutput Linear Systems With Input Nonlinearities

Adaptive low-gain integral control of linear systems with input and output nonlinearities

An adaptive low-gain integral control framework is developed for tracking constant reference signals in a context of nite-dimensional, asymptotically stable, single-input, single-output linear systems subject to locally Lipschitz, monotone input and output nonlinearities of a general nature: the input nonlinearity is required to satisfy an asymptotic growth condition (of suucient generality to ...

Low-gain integral control of continuous-time linear systems subject to input and output nonlinearities

Discrete-time low-gain control of linear systems with input/output nonlinearities

Discrete-time low-gain control strategies are presented for tracking of constant reference signals for "nite-dimensional, discrete-time, power-stable, single-input, single-output, linear systems subject to a globally Lipschitz, non-decreasing input nonlinearity and a locally Lipschitz, non-decreasing, a$nely sectorbounded output nonlinearity (the conditions on the output nonlinearities may be r...

Integral control of linear systems with actuator nonlinearities: lower bounds for the maximal regulating gain

Closing the loop around an exponentially stable single-input single-output regular linear system, subject to a globally Lipschitz and non-decreasing actuator nonlin-earity and compensated by an integral controller, is known to ensure asymptotic tracking of constant reference signals, provided that (a) the steady-state gain of the linear part of the plant is positive, (b) the positive integrator...

PD Controller Design with H¥ Performance for Linear Systems with Input Delay

This paper presents H∞ control problem for input-delayed systems. A neutral system approach is considered to the design of PD controller for input delay systems in presence of uncertain time-invariant delay. Using this approach, the resulting closed-loop system turns into a specific time-delay system of neutral type. The significant specification of this neutral system is that its delayed coeff...
