Nice Citations From Rosenbrock, H. H. (1974). Computer-Aided Control System Design, Academic Press, New York:
|
||
Solutions are constrained by so many requirements that it is virtually impossible to list them all. The designer finds himself threading a maze of such requirements, attempting to reconcile conflicting demands of cost, performance, easy maintenance, and so on. A good design usually has strong aesthetic appeal to those who are competent in the subject.</description>

High-Authority Control/Low-Authority Control
|
||
From (Andre Preumont, 2018):
|
||
The HAC/LAC approach consist of combining the two approached in a dual-loop control as shown in Figure 1. The inner loop uses a set of collocated actuator/sensor pairs for decentralized active damping with guaranteed stability ; the outer loop consists of a non-collocated HAC based on a model of the actively damped structure. This approach has the following advantages:
|
||
The active damping extends outside the bandwidth of the HAC and reduces the settling time of the modes which are outsite the bandwidth The active damping makes it easier to gain-stabilize the modes outside the bandwidth of the output loop (improved gain margin) The larger damping of the modes within the controller bandwidth makes them more robust to the parmetric uncertainty (improved phase margin)</description>
