In [1], design and analysis of
2DOF controller for split stator IM were executed and the electromagnetic parameters were determined.
Closed loop response of the system with or without the filter (b = 1), where
2DOF is the response received by using the method given in [8] and with PI the response received by using the proposed way of controller projection is shown in Fig.

2DOF system with base excitation.
The multimodal techniques can enlarge the bandwidth of operating frequencies of the vibration-based energy harvesters, for example, the piezoelectric energy harvester with a dynamic magnifier [137] and the
2DOF energy harvester with closed first and second mode frequencies [138, 139].
It contains Teaching Toolboxes with a derived mathematical model, a Simulink model and 1DOF and
2DOF PID controllers [7, 11], which are used as a link between the laboratory model, the physical (Simscape) model, and the graphic (3D Animation) model.
The initial cells are equipped to switch between high multisite testing of 3DOF magnetometer devices on a strip or 3DOF and
2DOF accelerometer devices in a carrier.
In matrix-vector form, equations of motion for the
2DOF sector (blade with the absorber) are given by Eq.
A two-degree-of-freedom (
2DOF) vehicle suspension system is used as shown in Figure 1.
Therefore, the whole system is a
2DOF oscillator with an SMA element, shown in Figure 1 [18, 22].
