“…Specifically, the proposed nonlinear models can be implemented with the motion control systems of the piezoceramic actuators of the Atomic Force Microscope to enhance the accuracy of the piezoceramic actuators. For the design of positioning manipulator-based piezoceramic actuators, the proposed nonlinear models can enhance the precision tracking control of these manipulators [4,5,6,11,12,13,14,16,19,24]. For example, the positioning accuracy of the ultramicroscopic imaging can be enhanced by considering the uncertainties due to the temperature effects in piezoceramic actuators [6].…”

High performance control requires high loop gain and large control bandwidth. However, the spurious resonances at the higher frequencies can limit the performance of such type of systems. This drawback can be overcome by using sensor fusion technique. In sensor fusion, two or more sensors are combined in synergy such that good performance is achieved at lower frequencies while ensuring robustness of the system at higher frequencies. This paper presents a new technique, termed as ''virtual sensor fusion", in which only one of the sensors is physically installed on the system while the other sensor is simulated virtually. The virtual sensor is selected based on desired high frequency response. The effectiveness of the proposed technique is demonstrated numerically for a case of active seismic isolation. A robustness analysis of virtual sensor fusion is also carried out in order to study its stability in the presence of spurious resonances. Finally, the technique is experimentally verified on active isolation of pendulum system from ground motion. The results obtained demonstrate good isolation performance at lower frequencies and robustness to plant uncertainties (spurious resonances) at higher frequencies. This technique can be effectively used for high precision control of sensitive instruments.

“…Magnetostrictive materials, a smart material, produce mechanical stress and strain when exposed to external magnetic fields [1]. Because of high energy density, large output strain/force, and ultrafast response (within several microseconds), magnetostrictive materials have been widely developed/studied in various applications, such as active vibration control [2] and ultrasonic positioning [3]. However, similar to other smart material-based actuators [4][5][6][7][8], such as piezoelectric ceramic-based actuators and shape memory alloy-based actuators, the magnetostrictive actuators behave strong hysteresis nonlinearity [9,10].…”

Hysteresis of the actuators based on magnetostrictive materials influences the control performance of the application systems. It is of importance and significance to establish an effective hysteresis model for the magnetostrictive actuators for precision engineering. In this paper, based on the analysis of the Duhem model, a first-order inertial system with hysteresis characteristic under harmonic input is used to describe the hysteresis caused by the inertia of the magnetic domains of magnetostrictive materials. Shape function is employed to describe the pinning of domain walls, the interactions of different magnetic domains of magnetostrictive materials, and the saturation properties of the hysteresis. Specifically, under an architecture of “inertial system + shape function” (ISSF-Duhem model), firstly a new hysteresis model is proposed for magnetostrictive actuators. The formulation of the inertial system is constructed based on its general expression, which is capable of describing the hysteresis characteristics of magnetostrictive actuators. Then, the developed models with a Grompertz function-based shape function, a modified hyperbolic tangent function-based shape function employing an exponential function as an offset function, a one-sided dead-zone operator-based shape function are compared with each other, and further compared with the classic modified Prandtl–Ishlinskii model with a one-sided dead-zone operator. Sequentially, feasibility and capability of the proposed hysteresis model are verified and evaluated by describing and predicting the hysteresis characteristics of a commercial magnetostrictive actuator.
