Model-less multivariable control (XMC) automates the way operating teams have always carried out multivariable constraint control and optimization manually. Notably, this method does not require detailed models or embedded optimizers. XMC uses patented rate-predictive control (RPC) internally. Courtesy: APC Performance LLC
