All ADwin systems make it possible to run fast digital open-loop controllers or closed-loop controllers. These controllers can run in parallel with other functions like data acquisition or signal generation on the same ADwin system. It's possible to run closed-loop controllers like PID, PI, cascade controllers, deatbeat controllers, adaptive controllers, and many others. The CPU's free programmable and multitasking capabilities makes it easy to run different controller types on the same system with different control cycle times. Therefore, for example, it's possible to run 20 PID controllers with 10kHz each, or many more with 1kHz, or only a few controllers with 50kHz, or a single controller with 400kHz. Obviously, the ADwin system offers sufficient performance to run many fast digital controllers in parallel with other tasks like signal generation or data acquisition. ADwin offers powerful solutions for open-loop controllers, too. Read any type of analog, digital, or counter input, calculate a freely programmable online formula, or use a lookup table, and write new values to analog or digital outputs.

Key features of control functions for open- and closed-loop controls

• Closed-loop controllers like PI, PID, cascade, adaptive, deat-beat, others
• Open-loop controller based on formulas or lookup tables
• Typical PID for speeds from 500Hz to 200kHz, max. PID speed 400kHz
• Multiple controllers simultaneously
• Different control algorithms and cycle times for parallel controllers
• Freely definable open-loop controllers
• Typical speed for open-loop controllers ranges from some kilohertz up to tmegahertz
• Controllers are 100% deterministic and reliable
