Dear List,

I am interested in knowing whether there are other alternative algorithms for control system applications other than the PID Algo. I know that a lot of work has been done in the application of fuzzy logic and neural network to solve control problem (feedback and feed forward).

1) Are there any other techniques?
2) What is the maturity level of the different techniques?
3) What are the market acceptance of the different algorithms?
4) and off course, what is the future for the control techniques?

Best Regards,

PID is the base of todays process control, simple because it gives you the most reliable means of bringing the parameter to where it is supposed to be.

There are multivariable controls. Yokogawa Blue star India I believe gives SMOC and other multivariable and advanced Process control options.

However such systems are generally setpoint adjustments.

Based Control systems. You can get the detailed text at the link PBC book.
