A method for PID controller tuning based on process models for unstable processes was introduced. The optimal. proportional and derivative gains of the AMBs were determined by the tuning method and utilized for the chatter stability analysis in order to search for the chatter-free cutting region. The stability analysis results showed that the optimal gains give wider chatter-free cutting region, and as a result the proposed tuning method was confirmed to be an effective tuning method for determining the optimal gains of the AMBs.

Since most real experimental situations are different from those of the simulations, it is required to modify control rules through experiments owing to uncertainties and unmodeled dynamics of the plant. This paper presents a convenient monitoring system which can display system responses exactly and test the performances of the control system. We design a PID controller using DSP board and propose a monitoring system based on PC and C++ Builder program. With the proposed monitoring system we can easily control the velocity of a DC motor system.
