This paper deals with an algorithm for decoupling multivariable systems based on generalized predictive control. Proposed control algorithm uses adaptive error weighting in cost function and reference change observation. From filtered reference it auto-tunes weight coefficients in order to reduce coupling between control loops. The algorithm is applied to greenhouse climate control; obtained simulation results show its efficiency.

This article suggests the application of input shaping for the elimination of electromechanical oscillations arising from changes in the operating point of the synchronous generator. Poorly damped poles are the cause of electromechanical oscillations of the synchronous generator. Various power system stabilizers (PSS) are now used to reduce the electromechanical oscillations. Input shaping is a feedforward control and therefore does not require the measurement of electrical and mechanical quantities of the synchronous generator unlike the PSS. It is possible to apply the input shaping for the excitation system of synchronous generators with or without PSS.
