Dead Beat and LQ Control Combination in Different Control Structures

J. Štecha and J. Roubal (Czech Republic)


LQ control, Dead Beat control, control structures.


It is well known that one degree of control structure has some principal limitation. For unstable plants it is not possible to obtain arbitrary transfer function of the whole feedback structure. On the contrary two degree of cont rol structure has no limitation concerning the stability of the plant. The aim of the paper is to show structure limi tation for dead beat and LQ control combination.
