The switching max-plus-linear (SMPL) system description is a powerful modelling tool for many applications that involve scheduling and synchronisation of cyclic discrete-event systems, such as manufacturing systems, traffic networks, printers, legged robots, queuing systems, and array processors. The switching mechanism of the SMPL system describes the switching of the SMPL system from one mode into another. In each mode the system is described by a max-plus-linear state equation and a max-plus-linear output equation, where a max-plus linear equation is an equation that is nonlinear in the conventional algebra, but linear in the so-called max-plus algebra. In each mode we have different system matrices, which means that in SMPL systems the routing of the events, the event order, and/or synchronisation may change due to uncertain events, state behaviour or due to control actions.
The project aims at developing new insights in the system-theoretical properties of SMPL systems in the presence of uncertainty, and at using this knowledge to develop new model predictive controllers for different types of uncertain SMPL systems. Uncertainty in the system parameters may occur when processing times (production times, transport times) are uncertain. Uncertainty in the switching may happen when routes are uncertain or process failures occur.
The research will require the use of skills in the fields of control of hybrid systems, max-plus linear algebra, graph theory, and stochastics.

Applicants should have the following qualifications:
• An MSc degree in systems and control, applied mathematics, mechanical engineering, electrical engineering, computer science, or a related field.
• Basic knowledge of control systems theory (this requirement may be waived if the candidate is particularly skilled in mathematics).
• Strong analytical skills and ability to work at the intersection of several research domains, in particular control systems theory and mathematics.
• Basic programming skills in Matlab are expected.
• Good command of the English language and communication skills are required.

Fixed-term contract: 4 years.
