| 總結: | The design of nonlinear control systems is a very important issue in control theory.
Until now, there is no generally accepted method in the design of nonlinear controls
for stability and tracking of system outputs. Therefore, in general, restrictions are
made for certain nonlinear classes. Bilinear systems are a simple class of nonlinear
systems. So that in this dissertation the study is limited to certain bilinear classes.
Non-minimum phase nonlinear systems are recognized as a major bottleneck
in many control design problems. There have been many control designs for
non-minimum phase nonlinear systems, including control designs based on the
gradient descent method, modified steepest descent method, iterative learning
control method, output redefinition method, and others.
This dissertation designs control on a particular class of bilinear systems using
input-output linearization and the bakstepping method. The design begins by
constructing a theorem to state the bilinear system non-minimum phase, minimum,
or weak minimum. In a minimum-phase bilinear system, the control design is
carried out by like a linear system. Whereas in the non-minimum phase system,
the control design is carried out using the backstepping method to determine the
control variables so that the system becomes stable and can track the desired output.
In addition, in this dissertation, the output is redefined so that the bilinear system
minimum phase.
From the research results, obtained several theorems from certain classes of bilinear
systems which show that the bilinear system is in a non-minimum, minimum or weak
minimum phase. Furthermore, the non-minimum phase system can be stabilized so
that it can track the desired output using the backstepping method. In addition,
obtained a theorem to state a minimum-phase bilinear system with a new output. |
