    Sammanfattning : This thesis deals with the problem of how to design a linear and time invariant controller (continuous- or discrete-time) for a SISO- or SIMO-system with amplitude constraints in the actuator. One of the basic ideas is to model the constraints by means of a 'disturbance' δ acting at the input of the process. LÄS MER
