Algebraic necessary and sufficient conditions for the controllability of conewise linear systems
Çamlıbel, Mehmet Kanat; Heemels, W. P. M. H.; Schumacher, J. M. (IEEE, 2008-04)The problem of checking certain controllability prop erties of even very simple piecewise linear systems is known to be undecidable. This paper focuses on conewise linear systems, i.e. systems for which the state space is ... -
Controllability of a class of bimodal discrete - time piecewise linear systems
Yurtseven, Evren; Çamlıbel, Mehmet Kanat; Heemels, W. P. M. H. (Elsevier, 2013-04)In this paper we will provide full algebraic necessary and sufficient conditions for the controllability/reachability/null controllability of a class of bimodal discrete-time piecewise linear systems including several ... -
Convergence of discrete-time approximations of constrained linear-quadratic optimal control problems
Han, Lashan; Çamlıbel, Mehmet Kanat; Pang, Jong-Shi; Heemels, W. P. M. H. (IEEE, 2010-12)Continuous-time linear constrained optimal control problems are in practice often solved using discretization techniques, e.g. in model predictive control (MPC). This requires the discretization of the (linear time-invariant) ... -
Disturbance decoupling of switched linear systems
Yurtseven, Evren; Heemels, W. P. M. H.; Çamlıbel, Mehmet Kanat (Elsevier, 2012-01)In this paper, we consider disturbance decoupling problems for switched linear systems. We will provide necessary and sufficient conditions for three different versions of disturbance decoupling, which differ based on which ... -
A full characterization of stabilizability of bimodal piecewise linear systems with scalar inputs
Çamlıbel, Mehmet Kanat; Heemels, W. P. M. H.; Schumacher, J. M. (Elsevier, 2008-05)This paper studies open-loop stabilization problem for bimodal systems with continuous vector field. It is based on the earlier work of the authors on the controllability problem for the same class of systems. A full ... -
Modelling, well-posedness, and stability of switched electrical networks
Heemels, W. P. M. H.; Çamlıbel, Mehmet Kanat; Van Der Schaft, A. J.; Schumacher, J. M. (Springer, 2003-04-03)A modeling framework is proposed for circuits that are subject to both time and state events. The framework applies to switched networks with linear and piecewise linear elements including diodes and switches. We show that ... -
Observer-based control of linear complementarity systems
Heemels, W. P. M. H.; Çamlıbel, Mehmet Kanat; Schumacher, J. M.; Brogliato, B. (Wiley - Blackwell, 2011-07-10)In this paper we present observer and output-based controller design methods for linear complementarity systems (LCS) employing a passivity approach. Due to various inherent properties of LCS, such as the presence of state ... -
On the controllability of bimodal piecewise linear systems
Çamlıbel, Mehmet Kanat; Heemels, W. P. M. H.; Schumacher, J. M. (Springer, 2004-03-25)This paper studies controllability of bimodal systems that consist of two linear dynamics on each side of a given hyperplane. We show that the controllability properties of these systems can be inferred from those of linear ... -
Stability and controllability of planar bimodal linear complementarity systems
Çamlıbel, Mehmet Kanat; Heemels, W. P. M. H.; Schumacher, J. M. (IEEE, 2003-12-09)The object of study of this paper is the class of hybrid systems consisting of so-called linear complementarity (LC) systems, that received a lot of attention recently and has strong connections to piecewise affine (PWA) ... -
Switched networks and complementarity
Çamlıbel, Mehmet Kanat; Heemels, W. P. M. H.; Van Der Schaft, A. J.; Schumacher, J. M. (IEEE, 2003-08)A modeling framework is proposed for circuits that are subject both to externally induced switches (time events) and to state events. The framework applies to switched networks with linear and piecewise-linear elements, ... -
A unified numerical scheme for linear - quadratic optimal control problems with joint control and state constraints
Han, Lanshan; Çamlıbel, Mehmet Kanat; Pang, Jong-Shi; Heemels, W. P. M. H. (Taylor & Francis, 2012)This paper presents a numerical scheme for solving the continuous-time convex linear-quadratic (LQ) optimal control problem with mixed polyhedral state and control constraints. Unifying a discretization of this optimal ...
