This paper is concerned with the design and implementation of an embedded system for automated reading of axes positions in machine tools. The system is known as DRO (Digital Read Out). Many workshops in industries still use manual machine tools such as lathe and milling machine to machining workpieces. The accuracy of such manual machine tools depends much on the reading accuracy of the operator operating them. As its consequence, the quality of the final workpieces decreases as operator makes accumulated mistakes in reading the axis. This problem can be reduced by using digital read out (DRO), that results in a more accurate and faster axes reading for a better and faster workpieces machining. In this paper, 4 axes DRO is designed using seven segment display. The 4 axes consist of 6 digits for x, y, z axis respectively, and 4 digits for the spindle speed. Seven-segment of 1 inch size for high visibility is used and is driven with some integrated circuits such as BCD to seven segment decoder and ULN2003 transistor. A multiplexing technique is selected to controls the display system. The embedded control is implemented in a microcontroller Atmega128. The novelty lies in the low cost, good accuracy, and is designed with embedded system design approach in mechatronics.

Networked control system (NCS) has received considerable attention in the last 15 years. The interest is stimulated by the fast development of communication in computer based control system technologies that offers many benefits in integrating production planning and control. Unfortunately, the network induces imperfections and constraints in control system implementation. One of these limitations which affects the NCS is varying communication delays. The paper shows the occurrence of varying time delays in wireline or wireless network and considers robust control design methods to handle the delay uncertainties.

The usage of proximity sensor for marker detections such as color line detection is the easiest technique in robotic competition. Most of the contestants use simple photo-reflective circuit as proximity sensor with constant light source and voltage-based threshold to deduce the presence of marker line. By using this technique, noises such as various changes in indoor lighting exposure and camera flash may cause negative effect against system performance. To overcome this situation, a proximity sensor model is presented utilizing photo-reflective circuit with modulated light source. Goertzel algorithm is then used to calculate the power spectrum value of the received signal from photo-reflective circuit. The presence of marker line is deduced by simple thresholding technique based on the previous calibrated power spectrum value. Using this model, marker line detection method based on proximity sensor becomes more robust against noises and disturbances.

In this paper we present a novel approach to improve the performance efficiency of a bottle processing assembly station by implementing smart sensor network. The use of smart sensors offers improvement in efficiency and reduces installation period. With implementation of smart sensor network it is possible to expand current network capacity with ease. This work incorporates a PLC used as parent control unit and microcontroller as DSCD to take care of smart sensor network and responsible for availability of data to parent control unit. The concept of wire break sensing has been implemented to identify the fault sensor. Thus it is easy to troubleshoot. Interlock logic ensures that mechanical parts do not get physically damaged.

In this paper, sliding mode control is utilized for stabilization of a particular class of polytopic differential inclusion systems with fractional-order-0<q<1. By defining a sliding surface with fractional integral formula, exploiting the concept of the norm of the state space, and obtaining sufficient conditions for stability of the sliding surface, a special feedback law is presented which enables the system states to reach the sliding surface and consequently creates a sliding mode control. Finally, performance of the method is illustrated using example and simulations

Mold cavity pressure in injection molding machine plays an important role in determining the quality of molded products. However, the dynamic of cavity pressure is time-varying in relation to the hydraulic servo-valve opening. A cavity pressure control scheme was proposed by applying Model-Reference Adaptive Control (MRAC) to deal with the time-varying nature of cavity pressure. The adjustment of controller gains was carried out by MIT Rule. A lead compensator was also employed to improve the transient response. The simulation demonstrated the effectiveness of MRAC-based system during filling and packing phases even in the presence of parameter variations, zero mismatches, and measurement noise. The actual cavity pressure response is able to follow the output of prescribed reference model with varied set point profile. In the future, the proposed control scheme is potential to be implemented in the real system.

This paper presents the design and experiments of a two-dimensional horizontal seismic sensor with spherical inverted pendulum and magnetic levitation. This pendulum become stable in vertical position due to the magnetic levitation, which is created by two magnetic rings composed by many small magnetic structures encircle the pendulum, with the same type of poles face to the same direction. The effectiveness of the sensor has been examined in detecting earthquakes sensed in the city of Bandung during the second half year of 2010. Two earthquakes signal from two different origin captured on 29 November 2010 and on 4 April 2011 are presented in this paper. Qualitatively, the two earthqukes can be clearly distinguished by comparing the amplitudes.

Synchronization of two fractional order hyperchaotic systems considering uncertainties and sector nonlinear inputs is investigated in this paper. A new fractional order sliding mode control scheme is proposed to synchronize two different fractional order hyperchaotic systems in the presence of uncertainties, sector nonlinearity in the control inputs. The stability of the error dynamics is proven using Lyapunov stability theorem. Simulation results are provided to verify the feasibility and effectiveness of the proposed synchronizing method.

In this paper the problem of cooperative tracking of multiple targets for multi-agent systems is investigated. Defining problem of target tracking as gathering maximum rewards associated with the targets, an optimization-based algorithm is presented. A cooperative receding horizon controller for reaching moving targets is proposed. Agents are controlled by adjusting their headings toward the moving targets. A notable advantage of the proposed approach is the estimations of target's motion and planning the agent's heading based on them. Simulation results are provided to verify the efficiency of the proposed method.
