Supervisory Predictive Controller, parallel SPC, cascade SPC, Process Control System, delay time.
The delay time on a water level control system was inconvenient to be elimi-
nated. This problem was occurred from natural process while the water was transferred
by pump via long pipe. Predictive control is a popular technique to control slow response
systems with delay time. This controller can applied in two level that are regulatory
and supervisory. In this research, comparison between PI and predictive controller in
regulatory and supervisory level with cascade and parallel configuration will analyze.
Implementation of this control method will be applied to level control systems PCT-
100. Predictive controller can eliminate the impact of delay time and improve system
performance with faster response. Predictive control in supervisory level with cascade
configuration has the best performance with the smallest time constant about 1.206 sec-
