Abstract
In recent years, Active Control (AC) research and applications have gained much
attention, e.g. Active Noise Control, Active Vibration Control and Active
Acoustic Structural Control. Due to the complexity of the acoustics, large
scale applications, such as actively canceling broad-band noise in a wide area,
still pose serious computational problems when using hardware which is not too
complex and expensive. For that reason we are looking for ways to reduce the
computational burden in AC systems for reducing the price and the complexity of
the hardware.
One of the methods we recently successfully investigated and which we deal with
in this paper, is the use of state space models instead of finite impulse
response models (FIR models) in AC systems. While FIR models are commonly used
in AC, they can require a large number of coefficients, deteriorating the
computational complexity, especially in poorly damped plants and/or broad-band
noise control applications. On the other hand, one of the advantages of state
space models is that they reduce the number of coefficients and the number of
computations dramatically due to their minimal parameterization.
In this paper we show how state space models can be used in AC systems and we
discuss their advantages compared to FIR models. We also illustrate our
approach for a vibrating plate structure.
