Tuning an H-Infinity Controller with a Given Order and a Structure for Interconnected Systems with Delays
Suat Gumussoy, Wim Michiels
An eigenvalue based framework is developed for the H-infinity norm analysis and its norm minimization of coupled systems with time-delays, which are naturally described by delay di…
Fixed-Order H-infinity Optimization of Time-Delay Systems
Suat Gumussoy, Wim Michiels
H-infinity controllers are frequently used in control theory due to their robust performance and stabilization. Classical H-infinity controller synthesis methods for finite dimensi…
Eigenvalue based algorithms and software for the design of fixed-order stabilizing controllers for interconnected systems with time-delays
Wim Michiels, Suat Gumussoy
An eigenvalue based framework is developed for the stability analysis and stabilization of coupled systems with time-delays, which are naturally described by delay differential alg…
Computation of Extremum Singular Values and the Strong H-infinity Norm of SISO Time-Delay Systems
Suat Gumussoy, Wim Michiels
We consider the computation of H-infinity norms for Single-Input-Single-Output (SISO) time-delay systems, which are described by delay differential algebraic equations. Unlike the…
Root Locus for SISO Dead-Time Systems: A Continuation Based Approach
Suat Gumussoy, Wim Michiels
We present a numerical method to plot the root locus of Single-Input-Single-Output (SISO) dead-time systems with respect to the controller gain or the system delay. We compute the…
Fixed-order H-infinity control for interconnected systems using delay differential algebraic equations
Suat Gumussoy, Wim Michiels
We analyze and design H-infinity controllers for general time-delay systems with time-delays in systems' state, inputs and outputs. We allow the designer to choose the order of the…
A Predictor-Corrector Type Algorithm for the Pseudospectral Abscissa Computation of Time-Delay Systems
Suat Gumussoy, Wim Michiels
The pseudospectrum of a linear time-invariant system is the set in the complex plane consisting of all the roots of the characteristic equation when the system matrices are subject…
Fixed-order strong H-infinity control of interconnected systems with time-delays
Suat Gumussoy, Wim Michiels
We design fixed-order strong H-infinity controllers for general time-delay systems. The designer chooses the controller order and may introduce constant time-delays in the controll…
On the sensitivity of the H-infinity norm of systems described by delay differential algebraic equations
Suat Gumussoy, Wim Michiels
We consider delay differential algebraic equations (DDAEs) to model interconnected systems with time-delays. The DDAE framework does not require any elimination techniques and can…
Continuation Based Computation of Root-Locus for SISO Dead-Time Systems
Suat Gumussoy, Wim Michiels
We present a numerical method to plot the root-locus of Single-Input-Single-Output (SISO) dead-time systems on a given right half-plane up to a predefined controller gain. We compu…
Computing the Pseudospectral Abscissa of Time-Delay Systems
Suat Gumussoy, Wim Michiels
The pseudospectra of a linear time-invariant system are the sets in the complex plane consisting of all the roots of the characteristic equation when the system matrices are subjec…
Computing H-infinity Norms of Time-Delay Systems
Suat Gumussoy, Wim Michiels
In this paper we consider the computation of H-infinity norm of retarded time-delay systems with discrete pointwise state delays. It is well known that in the finite dimensional ca…
Model-free control of nonlinear power converters
Loïc Michel, Wim Michiels, Xavier Boucher
A new "model-free" control methodology is applied to a boost power converter. The properties of the boost converter allow to evaluate the performances of the model-free strategy in…
Model-free control of microgrids
Loïc Michel, Wim Michiels, Xavier Boucher
A new "model-free" control methodology is applied for the first time to power systems included in microgrids networks. We evaluate its performances regarding output load and supply…
