“…Since the focus is on power, i.e., the rate of energy transport between components, bond graphs provide methods to model dynamic systems in different domains including electrical, electromagnetic, mechanical, hydraulic, etc., without discrimination. This helps in the analysis, identification, synthesis, and control of multi-domain linear and non-linear dynamic systems [16][17][18][19][20].…”

“…The motion speed is exceptional, and is limited only by the object's inertia, movement, and the output capability of the electronic driver. When operating in an energized condition, a piezoelectric actuator consumes a small amount of electrical power and produces limited heat [10][11][12].…”

The current study presents an adaptive control approach to solve the tracking trajectory problem for a robotic manipulator that uses a gripper based on bimorph piezoelectric actuators. The development of an adaptive gain state feedback form that considers the state restrictions is proposed using a novel class of barrier Lyapunov function that drives the effective control of joints and piezoelectric actuators. The proposed method allows for the inclusion of complex combinations of state restrictions in the Lyapunov function, yielding the construction of differential forms for the gains in the controller that can handle the evolution of trajectories of the robotic arm inside the restricted region. The proposed control design successfully tracks reference trajectories for both joints of the robotic arm as well as the motion of the piezoelectric device during several operative scenarios. A comprehensive experimental study evaluates the effect of introducing state-dependent gain considering state restrictions of the ellipsoidal type. The comparison of the mean square error confirms the contributions of the developed control action, showing better tracking quality for less control power with the same evaluation, which is a desirable characteristic in the controlled motion of micromanipulators. The proposed controller solves the tracking trajectory problem for the micromanipulation system, satisfies the motion restrictions, and allows better tracking performance to be enforced. Furthermore, comparison of the obtained trajectories seems to validate the proposed controller’s contribution concerning a feedback form with fixed gains.

“…189 material [11], [12]. The manoeuvre is essential to decrease the impact of vibration and preserve drivers by wasting this vibrational energy in dissipating heat [13]. Moreover, the whole suspension of the seat operates as a vibration isolator to remove the perturbation from high roughness of the road profile.…”

This work proposes a new piezoelectric transducer system with four freedoms of movement modelled and evaluated by mechatronic techniques. The proposed modelling techniques (finite element and bond graph) were performed in a 20-Sim framework attached to the ANSYS software. The established harvester system has the ability to increase the driver's comfort when travelling on several types of road surfaces. The piezoelectric harvester is designed to investigate and provide the health requirement and ride comfort of the vehicle's drives on random road surfaces. The simulation results affirm that the improved piezoelectric transducer arrangement is more productive for various aspects. The power recovery is significantly enhanced as well as the driving comfort on the three road categories. Finally, the harvestable power amount is highlighted and is graphically discussed for several specific applications.
