Control of Linear Systems with Saturating Actuators
This paper deals with the design of linear systems with saturating actuators where the actuator limitations have to be incorporated a priori into control design. We take a semi-global approach to solve some of the central control problems for such systems. These problems include: stabilization, input-additive disturbance rejection and robust stabilization in the presence of matched nonlinear un...
متن کاملDISTURBANCE REJECTION IN NONLINEAR SYSTEMS USING NEURO-FUZZY MODEL
The problem of disturbance rejection in the control of nonlinear systems with additive disturbance generated by some unforced nonlinear systems, was formulated and solved by {itshape Mukhopadhyay} and {itshape Narendra}, they applied the idea of increasing the order of the system, using neural networks the model of multilayer perceptron on several systems of varying complexity, so the objective...
متن کاملOutput Regulation of General Linear Systems with Saturating Actuators
This paper studies the classical problem of output regulation for linear systems subject to actuator saturation. The asymptotically regulatable region, the set of all initial conditions of the plant and the exosystem for which output regulation is possible, is characterized in terms of the null controllable region of the anti-stable subsystem of the plant. Feedback laws are constructed that ach...
متن کاملStabilization of exponentially unstable linear systems with saturating actuators
We study the problem of stabilizing exponentially unstable linear systems with saturating actuators. The study begins with planar systems with both poles exponentially unstable. For such a system, we show that the boundary of the domain of attraction under a saturated stabilizing linear state feedback is the unique stable limit cycle of its time-reversed system. A saturated linear state feedbac...
متن کاملAn LQR/LQG theory for systems with saturating actuators
An extension of the LQR/LQG methodology to systems with saturating actuators, referred to as SLQR/SLQG, where S stands for saturating, is obtained. The development is based on the method of stochastic linearization, whereby the saturation is replaced by a xed gain, calculated as a function of the variance of the signal at its input. Using the stochastically linearized system and the Lagrange mu...
