controller is widely used in many industrial
applications due to its simplicity in StmctllIe and ease
of design. However, it is difficult to achieve .the
desired control performance in the presence of
unknown nonlinearities, time delays, disturbances as
well as changes in system parameters. Consequently
several PID models have been suggested so at to
alleviate these effects on the performance of the PID
controllers. One such method is based on fuzzy logic
technique which is considered much more appropri.ate
when precise mathematical formulation is infeasible or
difficult to achieve. Furthermore, some applications
such as semiconductor packaging, computer disk
drives, and ultra-precision machining require a fast
and high precision processing. Consequently, there is
the need to consider digital signal processor (DSI?)-
based fuzzy PID for use in such applications. Design
and implementation of such technique is proposed in
this paper. Results of simulation studies haw
demonstrated the feasibility of this controller since: it
produces fast response with smooth motion control
