a. Internal Model Control (IMC) - use to control a single process variable to its setpoint using a single controller output (similar to PID control blocks)
b. Coordinated Control (CC) - use to control a single process variable to its setpoint using multiple controller outputs.
c. Modular Multivariable Control (MMC) - use to control multiple process variables to the setpoints using multiple controller outputs.
d. Cascade PID (PID2) - use to implement an outer loop/inner loop PID controller; sometimes two controllers can do a better job of keeping one process variable where you want it.
e. Multiple Parameter PID (PID+) - use more than one set of PID parameters to control a PID block.
f. Time of Day Pumping (TDP) - Optimize pumping schedules based on energy costs.
