Upgrading the orbit feedback system in the Taiwan light source

The global orbit feedback system plays a crucial role in the operation of the Taiwan Light Source (TLS). Various issues must be addressed to achieve maximize performance. The orbit feedback system was upgraded recently to meet increasing demand. Based upon operational experience during the last few years, a new system was designed to provide an environment for easy maintenance, real-time monitoring of performance, and trouble-shooting of the feedback loop. Highly robust and flexible controllers are now also supported. A general-purpose CPU real-time operation system has replaced the former DSP boards to reduce the resources required and provide a superior software development environment. Performance analysis tools were also developed to monitor system performance. Highly integrated commercial off-the shelf products (COTS) were used to support various beam studies and evaluation of the performance of the system. The implementation of these systems is discussed herein
