Abstract:
-
The design of any feedback control system with even modest
complexity requires simulation capability. The controlled plant and
feedback law are simulated in order to assess the possible effects of
discrepancies between the design model of the plant and the actual
plant, and in order to verify the correctness of design
approximations. In feedback system, the effects of such discrepancies
can be particularly serious and may be manifested as classical
instability in continuous-state systems, or as errors (trap states)
and/or loss of synchronization in discrete-state systems. Simulation
averts the most serious errors of these types because the control
system design can be corrected without physical damage to the actual
plant. Most simulations today are digital rather than analog.
