“…Another study of modeling the PDSS actuator was reported by Chang and Li [Chang and Li, 1999]. In this work, the friction between the end-effector and movable platform is Although some PDSS actuator models have been successfully developed to represent the displacement of the end-effector, none of existing models can represent the effect of AF surfaces which provides friction depending on the relative motion between end-effector and platform.…”

“…Ideally, the friction is infinite during the course of the PEA expansion such that the end-effector can stick with the platform, whereas it is zero during the course of the PEA contraction such that the end-effector can slip or slide on the platform. In reality, however, the working surfaces of existing PDSS actuators were all engineered by means of traditional manufacturing methods, resulting in the isotropic friction [Chang and Li, 1999].…”

Piezoelectric actuators (PEA) hold the most promise for precision positioning applications due to their capability of producing extremely small displacements down to 10 pm (1 pm = 10 -12 m) as well as their high stiffness and force output. The piezoelectric-driven stickslip (PDSS) actuator, working on the friction-inertia concept, has the capacity of accomplishing an unlimited range of motion. It also holds the promises of simple configuration and low cost.On the other hand, the PDSS actuator has a relatively low efficiency and low loading capability, which greatly limits its applications. The purpose of this research is to improve the performance of the PDSS actuators by employing specially-designed working surfaces.The working surfaces, referred as anisotropic friction (AF) surfaces in this study, can provide different friction forces depending on the direction of relative motion of the two surfaces, and are used in this research to accomplish the aforementioned purpose. To fabricate such surfaces, two nanostructure technologies are employed: hot filament chemical vapour deposition (HFCVD) and ion beam etching (IBE). The HFCVD is used to deposit diamond on silicon substrates; and the IBE is used to etch the diamond crystalloid with a certain angle with respect to the coating surface to obtain an unsymmetrical-triangle microstructure.iii A PDSS actuator prototype containing the AF surfaces was developed in this study to verify the function of the AF surfaces and characterize the performance of PDSS actuators. The designed surfaces were mounted on the prototype; and the improvement in performance was characterized by conducting a set of experiments with both the normal isotropic friction (IF) surfaces and the AF surfaces, respectively. The results illustrate that the PDSS actuator with the AF surface has a higher efficiency and improved loading capability compared to the one with the IF surfaces.A model was also developed to represent the displacement of the novel PDSS actuator.The dynamics of the PEA and the platform were approximated by using a second order dynamic system. The pre-sliding friction behaviour involved was investigated by modifying the LuGre

“…It is clear that the result from these works suggests that the Coulomb model for friction in PIFAs is not adequate. Other works such as Furutani et al (1998), Chang and Li (1999), and Jiang et al (2000), which also used the Coulomb model for friction, did not discuss the adequacy of the Coulomb model for frictional contact in PIFAs.…”

“…To date, there are three methods to deal with this issue in literature. The first method completely neglects the mass of the PA (Ha et al, 2005(Ha et al, , 2006Chang and Li, 1999;Jiang et al, 2000;Lambert et al, 2003;Edeler et al, 2011).

Abstract. This paper provides a comprehensive review of the literature regarding the modeling and control of piezoelectric inertia-friction actuators (PIFAs). Examples of PIFAs are impact drive mechanisms (IDMs) and friction-driving actuators (FDAs). In this paper, the critical challenges are first identified in modeling and control of PIFAs. Second, a general architecture of PIFAs is proposed to facilitate the analysis and classification of the literature regarding modeling and control of PIFAs. This general architecture covers all types of PIFAs (e.g., FDAs, IDMs) and thus serves as a general conceptual model of PIFAs. There is an additional benefit with this general architecture of PIFAs, namely that it is conducive to innovation in PIFAs, as new specific PIFAs may be designed in order to tailor to a specific application (for example, both FDAs and IDMs are viewed as specific PIFAs). Finally, the paper presents future directions in modeling and control for further improvement of the performance of PIFAs.

Abstract. Piezoelectric stick-slip actuators have become the foundation of modern micromanipulation. Due to difficulty in closed-loop control with manipulators that use piezoelectric stick-slip actuators, methods for open-loop control with a human in the loop have been developed. The utility of such methods depends directly on the accuracy of the open-loop models of the manipulator. Prior research has shown that modeling of piezoelectric actuators is not a trivial task as they are known to suffer from nonlinearities that degrade their performance. In this paper, we study the effect of static (non-inertial) loads on a prismatic and a rotary piezoelectric stick-slip actuator, and obtain a model relating the step size of the actuator to the load. The actuator-specific parameters of the model are calibrated by taking measurements in specific configurations of the manipulator. Results comparing the obtained model to experimental data are presented.
