CONTROL-CANONICAL-FORM METHOD APPLIED TO GENERATING SYSTEMS TO IMPROVE DYNAMIC STABILITY CHARACTERISTICS

The control-canonical-form (CCF) method is introduced for the purpose of applying it to high-order state-space single-input single or multip le-output (SISO or SIMO) and multiple-input multiple-output (MIMO) lin ear time-invariant system models to determine closed-loop systems (i.e . design robust controllers) from which enhanced dynamic stability cha racteristics and overall performance of these systems is achieved. The method has been applied successfully to a SISO 6th-order linearized s tate-space open-loop model (representing a simplified hydro power syst em), and to a MIMO 8th-order linearized state-space open-loop model (r epresenting an 87.5 kVA synchronous machine with conventional exciter supplying power to an electric utility system through an interconnecti on network).
