| Research Abstract |
In this research, we considered the design problem of multivariable linear controllers including PID controllers for multi-input/multi-output linear systems by using some number of frequency responses on frequency domain without using the exact mathematical model of the controlled plant. The main results are as follows:
(1) Theoretical results:
Some adjusting methods for the linear controller parameters based on the least-squares algorithm have been proposed by us. In this research, we extended and reformed the methods as follows. First, we applied a design method to the design of decentralized control systems. Second, we proposed a new controller design scheme based on frequency domain which guarantees stability of the resulting control system. In this case controller parameters are adjusted by using the constrained quadratic programming method.
(2) Experimental results:
We confirmed the effectiveness of the proposed methods through several experiments. These methods were applied w an active vibration control of carrier in warehouse which has flexible, structure, Further we applied the method to an active vibration control of a multi-degree-of-freedom structure. Through out those experiments, we could confirm the effectiveness and practical applicability of the proposed methods.
