Synchronous control of vibration motors has been realized using a microcomputer (PC) with a real time operating system (RT-Linux). The vibration motors are AC motors with centrifugal weights, and consist of two axes. Vector inverters drive the vibration motors. Based on the digital PID control theory, the PC calculates the velocity reference value for control of the vector inverters. Moreover, various motor control states were realized by adding vibration mode (maximum, middle, zero and backward direction rotation). Use of AT compatible small-sized single board microcomputer achieved a miniaturization and rich functions of the PC system. The real time processing of digital control attained in the function of the RT-Linux. The RT-Linux is extended the function of the Linux operating system, so the RT-Linux could realize a remote control by using the network function in the Linux. In this research, communication control between two personal computers connected to LAN and Ethernet was realized. By using RT-Linux for one personal computer, remote control with the real-time operation became possible. The UNIX network socket on Linux is used for the communication control, and TCP/IP is used as the communication protocol.
