The transport systems under consideration are conveyor belts or conduit systems in the process industry, which are used for material transportation between different process stages. During the transportation process, the material properties are modified by multiple control inputs in order to adjust required production conditions for subsequent process stages. The dynamical behavior of transport systems...
Transport systems with a spatially distributed control input are commonly used for the transport of material between different process stages and conditioning of the convoyed goods at the same time. Multiple-input multiple-output (MIMO) transport systems involve several actuator-sensor pairs along the transport path. In this paper, a model-based design approach for the control of MIMO transport systems...
Temperature conditioning systems are heat exchangers or heat spreaders, which are used for specific heating of flowing media. In practical applications heat from the actuator is often passed to the fluid with a spatial distribution. If the actuator dynamics are also considered in the model, the resulting model is a coupled Partial Differential Equation (PDE) system. The model includes transport of...
The automation of industrial finishing processes in automotive industry requires accurate control of temperature and humidity of the inlet air to guarantee constant product finish quality. Industrial heating, ventilation and air conditioning (HVAC) control systems are used to maintain the required operating conditions for the finishing process even in presence of changes of the ambient air conditions...
The article deals with the design of a feedforward controller for a transport system with spatially distributed control input considering input constraints. The feedforward controller is used to compensate transport delays in the input-/output (I/O) behavior of the transport system by realizing exact trajectory tracking of the nominal output along desired trajectories. The proposed method is based...
The article presents an approach for designing a feedforward compensation of a spatially distributed disturbance acting on a boundary controlled one dimensional heat conduction system. The disturbance affects the system behavior via a fixed spatial characteristic meaning that the spatial influence of the time dependent measured disturbance signal is a space dependent model parameter. The compensation...
The article presents a novel approach for designing an inversion based control for a distributed parameter system (DPS) described by a higher-dimensional inhomogeneous second order partial differential equation (PDE). The tracking task is to drive the output along a desired trajectory with a control input acting spatially distributed on the whole domain of the DPS via a fixed spatial characteristic...
The article presents an approach for designing an inversion based feedforward control for a distributed parameter system (DPS) described by a linear heat equation. The tracking task is to drive the output along a desired trajectory with the control input acting spatially distributed on the DPS via a fixed spatial characteristic. The inversion is derived from the zero dynamics of the DPS, which is...
