A LQG CONTROLLER DESIGN FOR LINEAR CONTINUOUS-TIME SYSTEMS BASED ON INPUT-OUTPUT DATA

摘要

In this paper, a new LQG control design based on input-output data for linear time invariant continuous-time systems is proposed. Considering the laguerre series expansion of input-output signals, the controller can be synthesized using only the coefficients by an algebraic calculation. The analysis of the system transformed by the laguerre series expansion is utilized to lead this design method. Comparing the proposed controller with the model-based one through a numerical simulation, the effectiveness is illustrated.
