AB  - The control law used in regular static state feedback is expressed in a novel direct form which is advantageous for the linearization of loudspeaker systems. Compared with the straightforward integrator-decoupled form, the direct form increases computational efficiency, requires fewer loudspeaker parameters, and can be easily implemented on signal processors working with a fixed-point format. The control law in the direct form can be applied to loudspeaker systems, with different acoustic radiation aids (closed-box system, vented-box system) and dispenses with measurement of the internal states and full identification of the acoustic parameters. The relationship between feedback linearization and feedforward filter techniques (Volterra filter, mirror filter) is discussed.
