This paper introduces a control system synthesis method for linear MIMO
systems with variable parameters and the impact of unmeasured external
disturbances, which is very common in industrial fields. For practical
applications, optimal control methods are often used for the system to
achieve the desired quality parameters. However, this method is limited
because it only guarantees the system's robustness when there are uncertain
dynamic components and many external effects. Therefore, with the above
class of systems, the article synthesizes control rules based on the
combination of optimal control and adaptive control to compensate for
uncertain components. The results are adaptive control law compensating for
the influence of variable parameter components, external disturbances, and
optimal controller for dynamic components with fixed parameters. The
article's proposed control system is simple, easy to implement, has high
control quality, and ensures optimal ability, adaptability, and good
interference resistance. Simulation results on Matlab Simulink software show
the correctness and effectiveness of the research results.
