To design an automatic controller of a tracking system usually can be built by analyzing response output system. However in many cases especially in complex dynamics system for example quadrotor controller, it is not trivial to end this. Control design for quadrotor can be done by modeling the dynamics system. When dynamics system can be modeled close to real system characteristics, then accurate...
Quad-copter is a type of Unmanned Aerial Vehicle (UAV) which has four rotors as its lifter. This type can do lot movements in the air while flying, such as yaw, roll, and pitch. This movement can work well by maintaining stability, direction, and the height of that quad-copter. Roll corner, pitch, and yaw are controlled so the quad-copter can move stably. Proportional Integral Derivative (PID) is...
Conventional PID controller is a simplest known controller and has been used in almost all process industries for controlling process parameter at desired set point. However, the weakness of the controller is largely depend on the parameter of the controlled object. As the dynamics process of a water tank is nonlinear, it also has nonlinear behaviour between the input and output. This paper demonstrates...
In this paper, a robust filter is designed using guaranteed cost method to deal with the problem on networked control system (NCS). NCSs are modeled by neutral-type systems with differentiable time-delay uncertainties. The control and gain filter are derived from LMI feasible solution. A numerical example is provided for illustration of the proposed condition.
Data services users are growing exponentially and the content accessed by the users are real time and multimedia communications. The most connection commonly used is wireless LAN IEEE 802.11. Quality of Service (QoS) is a mandatory requirement in Wifi to support network limited capacity. IEEE 802.11e introduce a new standard of QoS which is called Enhanced Distributed Channel Access (EDCA). This standard...
This paper presents the guaranteed cost filter of uncertain linear neutral systems. By discretizing the system, the work is an extension of the previous study on continuous case. We propose the robust Alter design via linear matrix inequalities (LMIs). Because the obtained inequalities have inverse relations, an LMI based iterative algorithm is used. A numerical example is given to illustrate the...
In this paper, we propose the implementation of PID on Networked Control System (NCS) using Particle Swarm Optimization (PSO) algorithm as tuning method. There are three modification of PSO that used in this paper. The first is Constant Inertia Weight of PSO (CIW-PSO), the second is Linear Difference Weight of PSO (LDW-PSO), and the latest is Random Inertia Weight of PSO (RIWPSO). In the end, we present...
This paper concerns on the problem of output feedback controller design for neutral systems. Generally speaking, not like a state feedback control problem, an output feedback control problem produces the non-convexity formulation in LMI so that it needs more complex computation. In this paper, we propose a sufficient condition for asymptotic stabilization by applying linear matrix inequalities (LMIs)...
This paper proposes the prototype design of a fire suppression system. The system uses temperature sensor LM35, gas sensor MQ-7 and microcontroller ATMega8535 as processing data from sensors. Environmental conditions such as temperature and CO gas concentration will be processed by the microcontroller and the data is sent by XBee Radio Frequency (RF) module and forwarded to the XBee RF server. The...
Today, the development of manipulator robot technology is growing fast and giving good impact for human life. Application of the manipulator robot technology can help many human's tasks effectively. However, most publications in this field of interest are based on complex computation, by using mathematical model from the actual robot. This paper proposes a control system for manipulator robot using...
This paper deals with the problem of robust guaranteed cost filter design for uncertain neutral systems with time-varying delay. The uncertainties are assumed to be norm bounded. We propose a sufficient condition for robust stability analysis and robust stabilization on the filter design, and the methods are derived in linier matrix inequalities (LMIs). The obtained result covers slow and fast time-varying...

This paper presents a design scheme of a full order observer-based guaranteed cost controller for uncertain linear systems, in which all state variables cannot be measured. The perturbations are assumed to be described by structural uncertainties. An iterative linear matrix inequality (ILMI) approach is used to design the observer-based controller. A numerical example is given to illustrate the proposed...
