Fakhruddin Mangkusasmito, Tsani Hendro Nugroho in this paper explain that One of the important control system in the manufacturing industry is the position control. Mainly in the Computer Numerical Control (CNC) machine, work-table motion control system is used to regulate work-table movements when the machine process a workpieces on it. On standard machines, work-table movements are two axes (X-Y), which is driven by a motor and lead-screw. The discussion in this research only focus on one axis assuming that the systems on both axes are the same and independent. In this research, MATLAB is used to describe the behaviour of the system and also to design appropriate control system in continuos system using state feedback linear controller such as pole placement , tracking system, full order compensator and reduced order compensator. The goal is to obtain a fast response with a rapid rise time and settling time to a step command, while not exceeding an overshoot of 5%. The specification are than a percent overshoot equal to1%, 0,05s settling time and 0,03s rise time. The performance of each control methods are simulated and analyzed to decide the best suit control method for the systems with such criteria. And the result verify that using tracking system controller method achieve such specification with 0% overshoot, 0,04s settling time and 0,028s rise time.

Internal temperature of electric panel practically depend on the amount of power dissipation generated by the panel components and the outside temperature. If this equilibrium is not maintained then the internal temperature can increase too high beyond the working temperature limit for components so as to shorten the life of panel components. Generally, there are two fans installed to circulate the air inside the panel that operates atÂ fixed speed. In order to improve fan energy efficiency, it is necessary to add a control system that can adjust the fan speed based on actual panel internal temperature. Efforts to increase energy efficiency are realized using cheap hardware and easily available on the market, the ATMEGA 8535 microcontroller and LM 35 temperature sensor. The fan speed is normalized in percent units and expressed virtually using the Pulse Width Modulation (PWM) signal value calculated by the proportional control algorithm inside the controller. The experimental results show that the PWM value can vary with actual panel internal temperature. Using the time constant temperature asumption k1 = 0.2, k2 = 0.4, k3 = 0.2, k4 = 0.2 and experimental data, it was shown by calculations that there was an increase in energy efficiency by 40.8%.

The identification system is a procedure to obtain a model of a system, then of the model will be validated to see the accuracy of the model is obtained, compared to the input-output results obtained from the experiments. In the identification system itself known two methods, the method of "non-parametric" and "parametric". On the other hand, DC motor is a type of motor that uses direct electric current to produce rotational mechanical energy and is widely used in various applications. In this study, input and output data acquisition will be performed on the Feedback brand DC motor, and the data will be processed so that the system model is obtained by the black box method. The data will then be processed with the help of MATLAB software. The input signal used in this experiment is Pseudorandom binary sequence (PRBS), which is used because it has a wide frequency range. The signal is generated by an arduino uno microcontroller. From the test results it was found that the validation of the non parametric system model with the correlation analysis method has a fitness value of = 83.19%, while the validation of the parametric system model with the least square ARX method has a fitness value of = 80.59%.
