RISOn the Determination of the Worst Allowable Persistent Bounded Disturbance for a System With Constraints
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: The problem of explicitly determining the worst persistent input disturbance that a closed-loop system can tolerate under prespecified state and control constraints is studied. Verification of ...
Multivariable Disturbance Rejection Tracking Controllers for Systems With Slow and Fast Modes
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: In this paper we consider the design of controllers for a class of singularly perturbed multi-input-multi-output linear time-invariant systems where the objective is asymptotic tracking in the ...
Construction of a Set of Nonovershooting Tracking Controllers
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: The problem of tracking a known reference without overshooting is of great practical importance in a number of applications. However, nonminimum phase systems and systems with reference inputs ...
Arbitrary Assignment of Eigenvectors With State Feedback
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Conditions under which eigenvectors of linear multivariable systems can be arbitrarily assigned using state feedback are derived. A procedure for obtaining the required feedback gain matrix is ...
An Explicit Minimum-Time Solution for the Simple Harmonic Oscillator
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: It is well known that the minimum time control of a simple harmonic oscillator subjected to a bounded control input is a bang-bang control where the input cannot remain constant for more ...
Design of Feedback Systems With Plant Input Rate Saturation via QFT Approach
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: In this paper, a synthesis approach for input rate saturation compensation of feedback systems is presented. Uncertain, stable plants of type greater than or equal to 1 are considered. Based ...
Design for Feedback Systems With Plant Input Amplitude and Rate Saturation
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: In this paper, a method of compensation for feedback systems subject to simultaneous plant input amplitude and rate saturation is presented. It applies to uncertain, stable plants of a type ...
A Frequency Domain Criterion for Robustly Stabilizing a Family of Interval Plants
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Considered in this paper is the problem of robust stabilization of a family of interval plants by a single fixed compensator. A frequency domain sufficient condition determines the closed-loop ...
A New Algorithm for Testing the Stability of a Polytope: A Geometric Approach for Simplification
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Considered in this paper is the robust stability of a class of systems in which a relevant characteristic equation is a family of polynomials F: f(s, q) = a0 (q) + a1 (q )s + [[ellipsis]] ...
Frequency Domain Design for Maximizing the Allowable Size of a Step Disturbance in Linear Uncertain Systems
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: A design methodology is developed for a linear, uncertain, SISO system for maximizing the size of a step disturbance in the presence of hard time domain constraints on system states, control ...
