In the presentation major difficulties of designing neural networks are shown. It turn out that popular MLP (Multi Layer Perceptron) networks in most cases produces far from satisfactory results. Also, popular EBP (Error Back Propagation) algorithm is very slow and often is not capable to train best neural network architectures. Very powerful and fast LM (Levenberg- Marquardt) algorithm was unfortunately...
This research is aimed at achieving human consciousness in a robot. The authors focus on mirror image cognition, which is a high-level conscious function of humans, and have been conducting mirror image cognition tests with the robot, and have discovered that emotion and feelings are closely related to decision-making and learning. However, do humans always decide on an action through their emotions?...
The plate-type electrostatic precipitators are often used in industry, especially at dedusting of high gas flows. An important application is in case of thermo-electrical power plants. The electrostatic charging of dust particles depends on more electric parameters, and its experimental determination is difficult. The electrostatic charging depends on the electric field's strength, on the dust particles'...
This paper investigates the application to the provision of integral discrete sliding mode tracking control with input constraint for engine idling speed control because the control logic are always implemented in discrete-time by microprocessors. The subject of this experiment is to improve the stability of the system against disturbances such as fuel purges and torque loads. A discrete Sliding mode...
This paper discusses a wireless control system for cooperative motion of machines, and clarifies the influence of packet loss on the system behavior. In performance evaluation, we focus on the synchronization of the motion of the fellow machines. In addition, using the nature of wireless, a new wireless control method is proposed for maintaining the performance under packet loss conditions. In the...
In this paper, we introduce an observer-based state of charge (SOC) estimator for batteries. The estimation strategy is based on the battery's state space model. This representation makes stability analysis easier for the proposed estimation technique. Unlike other estimation strategies, only battery terminal voltage and current measurements are required. Simulation results highlight the performance...
This paper introduces an adaptive DC bus voltage control strategy for renewable energy systems, combining different energy storage devices, i.e., batteries, fuel cells, and supercapacitors. Multiple bidirectional DC-DC converters accurate control is achieved with no source voltage sensing, which reduces the number of sensors. Unlike many adaptive controllers, the proposed strategy uses a single adaptive...
One of the problems for development of industrial controls programs is the availability of the actual equipment to be controlled. Availability of the equipment may be due to project timing, cost issues, and even location. By using a simulation tool, integrated with the control programming environment, the control engineer can test the control program functionality to reduce the amount of time required...
In this paper, an adaptive PID-Fuzzy Logic controller is proposed in order to control the angular displacement of an automobile Pierburg mechatronic actuator and achieve a wireless network control. This new PID-fuzzy logic controller topology takes advantage of the classical PID controller and the fuzzy logic technique which can improve the angular displacement precision and reduce the time delay...
The objective of this work is to demonstrate the use of acceleration feedback to improve the performance of a maglev system, especially in disturbance attenuation. In the single degree-of-freedom (DOF) system studied here, acceleration feedback has the effect of virtually increasing inertia, damping and stiffness. It is shown that it can be used to increase disturbance rejection without sacrificing...
This paper presents a hybrid modeling method for a pneumatic artificial muscle that vertically suspends a mass. The modeling mainly consists of mechanical and hydrodynamic equations and is developed with empirical modifications. A feature of this approach is that it allows the model to include if-then formulation and nonlinearity such as flow dynamics and friction. And the model includes a novel mass...
This article presents the design of Internal Model Controller (IMC) based Fractional Order Two-Degrees-of-Freedom controller with the desired bandwidth specification and the robustness of the designed controller is briefly analyzed. For the conventional IMC based PID controller, One-Degree of Freedom is sufficient to meet the desired bandwidth specification for both Servo and regulatory performances...
This study aims to replicate knowledge of operation for water supply system. The proposed method is able to extract knowledge of operation of experienced operators, and regenerate a plan of operation by using support vector regression. The proposed method can contribute to compensating for reduction of experienced operators.
This paper deals with the modeling, identification and control of the Pierburg mechatronic actuator. This actuator is used in the BMW M57 diesel engine to control all the air which are charged and entered in the vehicle engine. The actuator static characteristics are exploited to model the system dynamics. Then, the obtained model from the identification procedure is used to design a nonlinear control...
In this paper, we introduce a mathematical approach for modeling the bus priority system. The main objective is to highlight the problem of the bus priority dilemma. The mathematical approach is based on Petri Nets with inhibitor arc. Based on dioid algebra, we add a new constraint that models the resource sharing problem with a priority user. The system behavior is described by Minax[[γ,δ]]-linear...
