dc.description.abstractThis thesis investigates how the Linear Active Disturbance Rejection Controller (LADRC) can be used with the synchronous strategy for motion synchronization of multiple piezoelectric actuators (PEAs). Both a single PEA system and a three PEA system are used to validate the control system. The investigation consists of a brief introduction of the LADRC, system identication of a single PEA and three PEA system, parameter estimation of the LADRC, implementation of the LADRC for a single PEA and for a three PEA system with the synchronization strategy, a comparison between the LADRC using the synchronization strategy and Linear Quadratic Gaussian (LQG) using the synchronization strategy. The investigation demonstrated that the synchronized LADRC is a viable and simple control solution for the three PEA system, used to control the gap spacing between the mirrors of the Fabry - Perot Spectrometer own by SDCNLab in stratospheric balloon missions.
