        Analog PID controllers have been designed to make good use of position control in industries. Recently, the importance of digital position control is emphasized for the requirements of controller which are not only to control the objects but to include various aspects such as easiness of design and implementation, simple exchange of control program and convenient communications of data between various controllers and a host computer. This study proposes a combined control method which is mixed the vaiable structure control (VSC) with the PI control for minimum time position control of DC servo motor by microcomputer. The results of test by this method show offset-free and minimum time optimal position control which is not affected by the disturbance and the system parameter variations. The validity of the proposed method comparing with the conventional PID control is proved by the response experiments.

        The Variable Structure System(VSS) will be of much intrest to educators and design engineers who wish to demonstrate and investigate sophisticated position control methods and their applications. This paper describes DC motor position control by means of VSS concept. The control scheme is derived, implemented and tested in the laboratory where IBM AT computer has been used as a digital controller to control a representative servo system. The control system schematic is given and sample results are shown for illustration. This experiment may serve as a basis for further application of VSS.
