“…The internal model principle (IMP) states that the output of a closed-loop control system will asymptotically track a reference if the poles of the Z transform of that reference are embedded into the controller, without zero-pole cancellations [19,20,22]. The term 1 (z − 1)(z 2 − 2 cos(Ω)z + 1) in (28) contains the poles of a step and a sinusoidal signal with frequency Ω. Hence, a GPC strategy that satisfies (28) will track the desired reference.…”

Resonant controllers are widely used in power electronics to track sinusoidal references. According to the internal model principle (IMP), these controllers should embed the poles of the Laplace or Z transform of the reference for the closed-loop system to track the reference asymptotically. Thus, tracking a sinusoidal reference is difficult as the controller should adapt its structure to embed the poles of the sinusoidal reference with variable frequency, as those poles depend on that variable frequency. On the other hand, Generalized Predictive Control (GPC) is widespread in industry applications due to its fast response, robustness and capability to include constraints. Resonant controllers based on GPC, which satisfy IMP, have been developed. However, these controllers consider the sinusoidal frequency to be constant. This paper presents a new GPC-based resonant controller with an adaptive and simple control law to track references with variable frequencies. A PLL estimates the frequency of the reference. A multi-layer perceptron uses the estimated frequency to define the gain matrix required to calculate the GPC control action. The GPC control action and the estimated frequency define the control law, which satisfies IMP in steady-state conditions. The authors did not find in the literature the proposed mathematical development of an adaptive GPC resonant controller with a discrete-time augmented model whose control law satisfies IMP. Thus, the proposed approach is helpful to develop other adaptive predictive controllers. Experimental results show that the proposed controller can track sinusoidal references whose frequencies vary in time.

“…Independently of the action system, a microcontroller and electrical actuators are implemented in modern pipe organs as controllers of the registration and used to control the type and the volume of the sound [15]. Voice coil motor actuators (VCMs) are widely used in precision motion systems, miniaturization of electronic equipment and dynamic keyboard systems of musical instruments, which are known for their high-speed and high-precision positioning systems, as well as their simple design and easy control [16][17][18][19]. VCM actuators, which most commonly have a structure similar to hard disk drives (HDDs), are characterized by their small size in the direction of the rotational axis, allowing many actuators to be placed side-by-side in small spaces for miniature organ instruments [20,21].…”

In pipe organs, the oldest and most commonly chosen system for connecting the organist operator to the source of sound (i.e., the pipes to the action) is mechanical action. This article presents a mechatronic action with a voice coil motor (VCM) actuator to reproduce the action of a mechanical action on pipe organ. The mechatronic action makes it feasible to mechanically separate the keyboard from the pipes and to determine the control strategy for the mechatronic action by utilizing sensors, an actuator and a microcontroller. The time response of the organ pipe with mechanical action and the requirements for mechatronic action were outlined. The control strategy was preceded by measurements of the mechanical action and measurements of the behavior of the VCM actuator system, which moves the pneumatic valve pallet. Two control strategies, open-loop and closed-loop, were proposed and analyzed for the mechatronic action with the VCM actuator. According to the results, the suggested control strategies successfully reproduce the mechanical action’s behavior to a good extent.
