The linear 2DOF
bicycle model described in Equation 13 is used to derive the sliding control law.
In , 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  and with PI the response received by using the proposed way of controller projection is shown in Fig.

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  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.
The transformation matrix to build the reduced physical space and the reduced 2DOF
4th-order model are presented below.
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.
To compensate the loss of vehicle stability in emergency situations due to nonlinear characteristics of tire forces, a linear 2DOF
(Figure 8) vehicle plane model (bicycle model) with appropriate physical constraints is proposed as a desired model to be followed by the controller.
Therefore, the whole system is a 2DOF
oscillator with an SMA element, shown in Figure 1 [18, 22].
