Control of Delay Propagation in Railway Networks Using Max-Plus Algebra

In this thesis max-plus algebra is introduced and applied to the problem of controlling train delays. Two control strategies for the propagation of delays are discussed. The first is by letting certain trains run faster when a delay is detected, the second is by breaking connections between trains that have to wait for each other in order to...

The Longitudinal Static Stability and Control Characteristics of a Flying V Scaled Model: An Experimental and Numerical Investigation

Despite widespread research into the possibilities of improving aerodynamic efficiency, a plateau seems to have been reached for the conventional configuration. Hence, the potential of unconventional configurations are being investigated in recent years. Flying V is one such configuration that promises a lift to drag ratio about 24 in cruise...

Model-Based Control of Industrial Batch Crystallizers: Experiments on Enhanced Controllability by Seeding Actuation

Crystallization is one of the oldest separation and purification techniques. Batch crystallizers are widely used in production of fine chemicals, food ingredients, specialty chemicals, and active pharmaceutical ingredients. Control of the crystalline material properties is a challenging task due to complexity and nonlinearity of batch...
