Optimised State-Dependent Sampling Control for Heavy-Haul Trains

This thesis investigates the potential of state-dependent sampling strategies (SDSS) for the control of heavy-haul trains. Event-triggered control (ETC) is a control approach in which data is only sent when some state-dependent condition, the triggering condition, is satisfied. In this way, the number of communications required to stabilise a...

Formal Synthesis of Event-Triggered Controllers

In networked control systems (NCS), the components of the control system communicate over a network, which poses challenges to the control synthesis procedure. Signal sampling is one of those challenges. A typical approach is to sample the signal periodically, but this can be inefficient. Event-triggered control (ETC) is a more efficient way to...

Scheduling Strategies for Event-Triggered Control Using Timed Game Automata Over CAN Networks

Modern times have seen an increasing use of networked control systems, in which plants and controllers may not necessarily have a direct link but instead be connected through a network, thereby closing control loops over multiple nodes.<br/><br/>The system may also be spread out spatially over a large area, and thus the associated network delays...

Automating scheduler design for Networked Control Systems with Event-Based Control: An approach with Timed Automata

As the use of Networked Control Systems increases, the need for control methods with more efficient network usage also grows. These methods require a more sophisticated way of pre- dicting their traffic, and an approach for this is using a formal modelling approach using Timed Automata. Timed Automata have been used for over 25 years for several...

Event-Triggered Control for Vehicle Platooning: Application to heterogeneous platoons

This thesis covers the implementation of Event-Triggering Control (ETC) on Cooperative Adaptive Cruise Control (CACC). CACC has the potential to increase road capacity, by having safe vehicle following with small intervehicle distance (less than 1 second), to increase traffic flow by eliminating shockwave effects, such that string-stable...

Abstraction of In-Vehicle Event-Triggered Networked Control Systems for Scheduling

The number of electronic control systems applied in vehicles has increased dramatically over<br/>the years. This trend will only continue with the introduction of novel technologies such as<br/>advanced driver assistance systems (ADAS). To save cable weight and costs in-vehicle control<br/>systems often use shared communication networks. With...

The impact of event-triggered control on the energy consumption of a legged robot

In event-triggered control (ETC) the control task is only executed when needed to ensure performance or stability. A well known property of ETC is that it can reduce the number of control task executions while retaining similar performance. A large amount of research is focused on how ETC can be used to achieve energy savings in wireless...
