Universal Control Law and Rate Feedbacks
A common approach to control problems is to look for a static control
law through a detailed study of the known mathematical model of the system,
assuming that the needed measurements of the state vector are available
for closed-loop feedbacks. Recently, this author showed that a special
control law can control a class of systems without the need of detailed
knowledge of their mathematical models---provided good quality measured
rate data of certain components of the state vector are available. The
present paper shows that when additional knowledge beyond the minimum is
available, the amount of needed rate data can be reduced. Numerical simulations
are presented to elucidate the effects of measurement noises.
