| Abstract: |
| We present in this article a MATLAB toolkit with a user-friendly graphical interface for composite nonlinear
feedback control system design. The toolkit can be utilized to design a fast and smooth tracking controller for a
class of linear systems and nonlinear systems with actuator and other nonlinearities as well as with external disturbances.
The parameters of the controller can be tuned easily on the user panel or autotuned by the toolkit. The toolkit is capable of
displaying both time-domain and frequency-domain responses on its main panel and generating three different types of control
laws, namely, the state feedback, the full-order measurement feedback and the reduced-order measurement feedback
controllers. The usage and design procedure of the toolkit are illustrated by practical examples on a rotational/translational
actuator (RTAC) system and a hard disk drive servo system. The toolkit can be utilized to design servo systems that deal
with point-and-shoot fast targeting. |
