A method for controlling a chemical reactor such as a gas-phase reactor using a non-linear predictive control includes steps for generating a plurality of signals representing a current state of the chemical reactor and reflecting a respective constituent of reactants in the chemical reactor, calculating a future state of the chemical reactor responsive to said plurality of signals and referenced to mass hold-up of the reactants in the chemical reactor, and controlling at least one parameter related to the chemical reactor so as to control the future state of the chemical reactor. Spurious control events due to noise in sensor or controller output signals are preferably minimized by filtering these signals using a N-sign filter subroutine.
