Working from within: Benefits of a performance assessment solution embedded to a field device

摘要

Only by consistent and systematic monitoring is it possible to obtain confidential information about the target process. Users especially monitor process control with low-level control loops to mainatain an adequate level of control performance. Online performance monitoring and diagnostics could improve control performance in general, especially when more sophisticated high-level control procedures such as model predictive or fuzzy controllers use low-level controllers (PID controllers) as slaves to fulfill their commands.
