Books have been written about each of these sub-topics and many standards exist to specify best practices or provide guidance. The Instrumentation, Systems and Automation Society (ISA) is the primary professional society that addresses many of these different aspects of process control. The focus of this chapter will be on control loop principles, loop tuning, and basic control strategies for continuous processes. 

International standard symbols for instruments, controllers, and valves are given by the Instrumentation Systems and Automation Society design code ISA-5.1-1984 (R1992). Some companies use their own symbols though, and different standards are followed in some countries, such as BS 1646 in the UK and DIN 19227 and DIN 2429 in Germany (see references).
