Chapter 14
Multivariable Control
The performance of single-loop control systems is often limited by time-delays and right-half-plane zeros in the input-output dynamics. Similarly, multiple-loop control system performance can be limited by time-delays, right-half-plane transmission zeros and the “direction” of the setpoint changes. Since the manipulated inputs and measured outputs may have different units and operating ranges, it can be important to scale these variables to span similar ranges.
After studying this chapter, the reader should be able to
Understand the performance limitations of processes with right half-plane (RHP) transmission zeros.
Understand the effect of “direction” in a multivariable system.
Perform matrix transfer function ...
