Robust Controller Design for Multi-Input Multi-Output Systems Using Coefficient Diagram Method [PDF]
Entropy, 2021 The coupling between variables in the multi-input multi-output (MIMO) systems brings difficulties to the design of the controller. Aiming at this problem, this paper combines the particle swarm optimization (PSO) with the coefficient diagram method (CDM)
