— This paper introduces a new Matlab Toolbox called RobSin, which for a given plant (multi-)model provides a fast computation of the stabilizing region in the coordinates of PID parameters. The algorithms use the concept of singular frequencies for computation of convex polygonal slices on planes k P = const. In addition to time-continuous systems, the(More)
The topic of this paper is distributed state estimation for time-invariant systems with finite input and output spaces. We assume that the system under investigation can be realised by a hybrid I/S/O-machine, where some of the discrete states may also represent failure modes. Our approach is based on previous work, e.g., Moor and Raisch (1999); Moor et al.(More)
Ahstract-A symbolic approach to decentralized set-valued state estimation and prediction for systems that admit a hybrid state machine representations is proposed. The decentralized computational scheme represents a conjunction of a finite number of distributed state machines, which are specified by an appropriate decomposition of the external signal space.(More)
— A comprehensive theory for robust PID control in continuous-time and discrete-time domain is reviewed in this paper. For a given finite set of linear time invariant plants, algorithms for fast computation of robustly stabilizing regions in the (k P , k I , k D)-parameter space are introduced. The main impetus is given by the fact that non-convex stable(More)
