Abstract: For the design of multi-input multi-output (MIMO) system, two major tasks have to be resolved, i.e., loop pairing and controller design. For the first task, one needs to pair the input and output variables in such a way that the interactions among different loops are smallest. The other task is control system design according to paired variables. Generally, a good pairing results in relatively easy controller design. Unfortunately, both loop pairing and controller design are difficult since there are complicated interactions among different loops. Especially for controller design, adjusting controller parameters of one loop will affect the performance of others, sometimes to the extent of destabilizing the entire system. To ensure stability, many industrial controllers for multivariable processes are tuned loosely, which causes inefficient operation and higher energy costs.
