Electromagnetic actuator systems composed of an induction servo motor (ISM) drive system and a rice milling machine system have widely been used in agricultural applications. In order to achieve a finer control performance, a witty control system using a revised recurrent Jacobi polynomial neural network (RRJPNN) control and two remunerated controls with an altered bat search algorithm (ABSA) method is proposed to control electromagnetic actuator systems. The witty control system with finer learning capability can fulfill the RRJPNN control, which involves an attunement law, two remunerated controls, which have two evaluation laws, and a dominator control. Based on the Lyapunov stability principle, the attunement law in the RRJPNN control and two evaluation laws in the two remunerated controls are derived. Moreover, the ABSA method can acquire the adjustable learning rates to quicken convergence of weights. Finally, the proposed control method exhibits a finer control performance that is confirmed by experimental results.

Abstract Circular disk is a basic mechanical element, which is used widely in industry such as turbine machine, circular saw, and computer memory. Considering the requirements for the actuator to control the transverse vibration of circular disk, the non-contact electromagnetic actuator which can produce large actuating force is used, and a whole set of control system that is composed of analog components is built. The good experimental results are obtained by using the control system to control the transverse vibration of circular disk.

General Method

In this paper, we deal with the problem of active damping of vibrations of a continuous viscoelastic structure, and a general method of computation of the control system is developed. We define a mechanical model for this structure, the sources of perturbing vibrations, the control system, and different absorption criteria. The problem is set in an infinite dimension space, and an approximation problem is derived in n dimension spaces. Two methods of resolution are proposed for this approximation problem, and the solutions are compared. An example is given for the case of flexural vibrations in beams. Numerical results simulating the behavior of flexural vibrations in a rectangular plate, which is simply supported along the whole boundary, are presented for three different absorption criteria, thus permitting a quick evaluation of the comparative effectiveness of the chosen criteria.

This paper presents the virtual prototype of the mono-axis tracking system used for improving the efficiency of a string of photovoltaic modules. The solar tracker simultaneously changes the daily position of the modules, using a linear actuator that drives a rack-pinion mechanism. The key in optimizing the tracking system is to maximize the received solar radiation and to minimize the energy consumption for tracking. The virtual prototype is developed using a digital platform which integrates the following software solutions: CATIA - for the solid modeling of the components, ADAMS - for developing the mechanical model in MBS (Multi-Body Systems) concept, and MATLAB/Simulink - for the control system design.

A new 4WS vehicle model is set up by means of revamping a foreign FWS model. Co-simulation is completed by loading 4WS mechanical model as a subsystem which is built to express the characteristics of physical model of vehicle in ADAMS/Car into the control system modeled in MATLAB. Moreover, the response curves of evaluating handling stability are obtained according to co-simulation results of step steering maneuvers and single lane change maneuvers. It provides theoretical basis for developing 4WS physical vehicle rapidly.

Jib Crane is a type of machinery used mainly to raise or lower materials or heavy objects and to carrying them to other places. It is used in construction and in the installation of large machines such as wind turbines and harbors, and is an essential component of integrated production processes. Because of the large loads carried by these cranes it became necessary to know their behavior before investment by studying their movements and studying the vibration of payloads and work to reduce them as much as possible and thus prolong the life of the crane components and increase their efficiency. Hence the need to design a control system to dampen load vibration to reduce the impact of dynamics affecting the parts of the crane. In this research, the mathematical model similar to the mechanical model of the crane was prepared and solving the model using MATLAB program, and then design a proportional integral differential controller for jib crane

Road Disturbance

The main purpose of using the suspension system in vehicles is to prevent the road disturbance from being transmitted to the passengers. Therefore, a precise controller should be designed to improve the performances of suspension system. This paper presents a modeling and control of the nonlinear full vehicle active suspension system with passenger seat utilizing Fuzzy Model Reference Learning Control (FMRLC) technique. The components of the suspension system are: damper, spring and actuator, all of those components have nonlinear behavior, so that, nonlinear forces that are generated by those components should be taken into account when designed the control system. The designed controller consumes high power so that when the control system is used, the vehicle will consume high amount of fuel. It notes that, when vehicle is driven on a rough road; there will be a shock between the sprung mass and the unsprung mass. This mechanical power dissipates and converts into heat power by a damper. In this paper, the wasted power has reclaimed in a proper way by using electromagnetic actuator. The electromagnetic actuator converts the mechanical power into electrical power which can be used to drive the control system. Therefore, overall power consumption demand for the vehicle can be reduced. When the electromagnetic actuator is used three main advantages can be obtained: firstly, fuel consumption by the vehicle is decreased, secondly, the harmful emission is decreases, therefore, our environment is protected, and thirdly, the performance of the suspension system is improved as shown in the obtained results.
