We present an interactive audio game designed around the auditory perception of distance and the use of physics-based models for simulations of the dynamics, the sound source, and the acoustical environment. The game consists in throwing a virtual sounding object inside a virtual open-ended tube which is inclined. The task is to keep the object inside the tube, in other words the user should ad...
In this paper, an adaptive neural command filtered backstepping scheme is proposed for the pneumatic active suspension with vertical displacement constraint of sprung mass and actuator saturation. A quarter car model a spring first fabricated on basis thermodynamic theory to describe dynamic characteristics. To overcome lumped unknown nonlinearities enhance requirement modeling precision, radia...
We have studied a stacked-type electrostatic actuator by folding two ribbon electrodes in an alternate configuration. The energy efficiency of this type of actuator was investigated using the thick-electrode-part actuator and triangle-shaped actuator. The maximum energy efficiency levels were 30–40% for the thick-electrode-part actuator and 40–50% for the triangle-shaped actuator.
This paper studies the design of a robust output feedback controller subject to actuator saturation. For this purpose, a robust high-gain sliding mode observer is used to estimate the state variables. Moreover, the combination of Composite Nonlinear Feedback (CNF) and Integral Sliding Mode (ISM) controllers are used for robust output tracking. This controller consists of two parts, the CNF part...
s--By making the controller adaptive, ideal performance and granted stability of the closed loop system can be achieved for even a large change in system parameters. In the present study, adaptive controllers based on minimum variance, pole placement and linear quadratic techniques are investigated. The controller based on minimum variance is noise sensitive and actuator voltage changes sign af...
This paper presents a novel approach for designing reconfiguration blocks fault hiding of linear systems subject to actuator faults based on the passivity/dissipativity theory. For this purpose, concept passivation block is used design virtual actuators (VAs) which guarantee that faulty plant achieves desired passivity indices and consequently stability. Linear matrix inequalities (LMI)-based c...
The evolution of automation systems has reached a point where the increasing complexity requires new mechanisms to keep control of design and operation. In future all control systems will have to cope with massive data quantities that are collected from the environment. Such systems have to react based on the recognition of whole scenarios. In this paper we present a simulation tool, which is a...
Tactile displays are used to provide tactile feedback in telemanipulation or virtual reality. One aim in further developments is the miniaturisation of tactile displays for incorporation into dataand/or force feedback gloves. This enables the combination of tactile and kinesthetic feedback. A main disadvantage of many tactile displays with a large number of stimulator elements is their large vo...
Abstract Purpose This study improves the robustness of model-free controller based on a virtual structure. Additionally, adverse interference between proof-mass actuator resonance and controlled object is investigated as it not clarified in previous studies. Methods Results A structure modeled SDOF system was inserted actual object. achieved indirect damping control. Vibration control simulatio...
in this paper a novel direct adaptive fuzzy system is proposed to control flexible-joints robot including actuator dynamics. the design includes two interior loops: the inner loop controls the motor position using proposed approach while the outer loop controls the joint angle of the robot using a pid control law. one novelty of this paper is the use of a pso algorithm for optimizing the contro...
