This paper presents an attitude control algorithm for a Reusable Launch Vehicle (RLV) with a low lift/drag ratio (L/D < 0.5), in presence of external disturbances, model uncertainties, control output constraints and the thruster model. The main novelty of the proposed control str
A robust override scheme enforcing strict output constraints for a class of strictly proper systems
This paper presents an override controller which ensures that constrained output variables retain certain prescribed strict bounds. The class of nominal closed loop systems considered for the constrained output regulation problem is strictly proper and minimum phase, assuming for
Output violation compensation for systems with output constraints
The problem of output constraints in linear systems is considered and a new methodology which helps the closed loop respect these limits is described. The new methodology invokes ideas from the anti-windup literature in order to address the problem from a practical point of view.
Transformation of Output Constraints in Optimal Control Applied to a Double Pendulum on a Cart
This paper describes a constraint transformation technique for optimal control problems (OCP) with nonlinear single-input single-output (SISO) systems subject to output constraints. An input-output transformation and saturation functions are used to transform the system dynamics
The Fault-Tolerant Control of Magnetic Bearings With Reduced Controller Outputs
The fault-tolerant control scheme utilizes grouping of currents to reduce the required number of controller outputs. Reduced current distribution matrices can be calculated with the constraint conditions of the controller outputs and the necessary condition for linearization. Dec
An Optimal Augmented Monotonic Tracking [1.0]Controller for Aircraft Engines with Output Constraints
This paper proposes a novel min-max control scheme for aircraft engines, with the aim of transferring a set of regulated outputs between two set-points, while ensuring a set of auxiliary outputs remain within prescribed constraints. In view of this, an optimal augmented monotonic
Affine Feedback Policies for Robust Control with Constraints
This thesis is concerned with the optimal control of linear discrete-time systems with convex state and input constraints and subject to bounded disturbances. It is shown that the nonconvex problem of finding a constraint admissible affine state feedback policy over a finite hori
Optimal Tuning Parameters of the Dynamic Matrix Predictive Controller with Constraints
−− Dynamic Matrix Control Algorithm is a powerful control method widely applied to industrial processes. The idea of this work is to use the Genetic Algorithms (GA) with the elitism strategy to optimize the tuning parameters of the Dynamic Matrix Controller for SISO (single-input
Nonlinear model based/model predictive control with constraints and with/without nonlinear observer
A literature survey from the area of nonlinear model predictive control (MPC) is presented. After a brief review of the main characteristics of linear MPC algorithms various classes of nonlinear MPC algorithms based on state-space models, such as nonlinear extensions of dynamic m
Nonlinear Fed-batch Reactor Pi Control with Constraints
This work studies the control of a fed-batch reactor for the production of penicillin and the design of suboptimal control strategies which result simple for their implementation. These strategies are able to (i) generate a suboptimal control that lead to the batch process toward
