In a general aspect, a system includes a controller configured to receive a first signal representative of a load on an engine and to generate a control parameter based on the first signal, one or more harmonic scaling elements, each configured to receive the control parameter and a different engine harmonic signal of a plurality of engine harmonic signals and to generate a scaled version of the received engine harmonic signal. Each, harmonic scaling element includes a harmonic specific mapping element for mapping the control parameter to a harmonic specific scaling factor, wherein at least some of the harmonic specific scaling factor values of the harmonic specific mapping element are mapped to control parameter values which are associated with a negative load on the engine, and an adjustable gain element for forming a scaled version of the received engine harmonic signal including applying the harmonic specific scaling factor to the received engine harmonic signal. The controller is further configured to condition the first signal to remove transient components before generating the control parameter.
