“…The dynamic characteristic for a throw will be investigated with a simulation. For the belt driven actuator several models are already available in different research works [7,8,9,10,11]. They are optimized for special conditions like variable loads, nonlinear frictions or high precision controls.…”

In a research project we are working on the development of a new technology for the transportation of objects within production systems by throwing or shooting. At the current state of the work objects with masses up to 70 g are thrown with speeds up to 10 m/s over distances up to 3 m. Therefore a prototype of a mechanical throwing device with a spring was realized. At this device the characteristics for the acceleration of the objects can be modified only by mechanical settings. To improve this, in this paper the concept for a numerical controlled throwing device is presented. It includes a commercial available belt driven linear actuator. Since the elasticity of the belt has a significant influence to the dynamic characteristic of such an actuator the motion for throwing an object was simulated.

“…This assumption is made because the mass of the timing belt (about 4 g) relative to the mass of the rest of the system is insignificant. Belt compliance needs to be taken into account in systems that have large loads and high speeds [9]. This system has small loads with low speeds.…”

An adaptive recurrent radial basis function network (ARRBFN) tracking controller for a two-dimensional piezo-positioning stage is proposed in this study. First, a mathematical model that represents the dynamics of the two-dimensional piezo-positioning stage is proposed. In this model, a hysteresis friction force that describes the hysteresis behavior of one-dimensional motion is used; and a nonconstant stiffness with the cross-coupling dynamic due to the effect of bending of a lever mechanism in x and y axes also is included. Then, according to the proposed mathematical model, an ARRBFN tracking controller is proposed. In the proposed ARRBFN control system, a recurrent radial basis function network (RRBFN) with accurate approximation capability is used to approximate an unknown dynamic function. The adaptive learning algorithms that can learn the parameters of the RRBFN on line are derived using Lyapunov stability theorem. Moreover, a robust compensator is proposed to confront the uncertainties, including approximation error, optimal parameter vectors, higher-order terms in Taylor series. To relax the requirement of the value of the lumped uncertainty in the robust compensator, an adaptive law is investigated to estimate the lumped uncertainty. Using the proposed control scheme, the position tracking performance is substantially improved and the robustness to uncertainties, including hysteresis friction force and cross-coupling stiffness, can be obtained as well. The tracking performance and the robustness to external load of the proposed ARRBFN control system are illustrated by some experimental results.
