“…The PI controller for constant load milling was designed based on the machining system dynamics. This study used LabVIEW [38] to create the chirp signals and the block diagram of the program is shown in Figure 3, where f1 and f2 were the start and end frequencies of the chirp signals, respectively. The input signal was the voltage signal for controlling the feedrate.…”

The traditional method of milling which uses constant spindle speed and feedrate to prevent machine, workpiece, and machining tool failure. However, this method prevents engineers from further improving machining efficiency. It is possible to increase machining efficiency by appropriately adjusting feedrate during the machining process. Although there are plenty of researches regarding adaptive machining force control, those researches focus on the design of controller, and few of them discuss the relation between control signals and tool wear for parameters setting. This study presents a method for setting process parameters in constant load machining, including feedrate upper and lower limits, as well as reference spindle current. The reference spindle current and feedrate upper limit were selected to sustain cutting force up to tool strength. The feedrate lower limit was established to maintain tool wear conditions within a given range, preventing severe and unstable tool wear. The experimental results showed that when the feedrate was reduced to the lower limit value, the machining parameters setting method presented in this study could keep the tool wear within the set value, avoiding the risk of tool failure. The strategy for setting the machining parameters can be used to end milling, slot milling, or a combination of both milling processes. The constant load machining parameters presented in this study outperformed constant feedrate machining of the identical milling conditions in terms of tool life and material removal rate. The traditional method estimated tool life by cutting lengths, but we used the feedrate change to estimate the tool wear for change. The result showed that this method had better tool life than traditional way.

“…For the accuracy of the angle of attack against the setpoint is good enough although there is still a difference of about 0.5⁰. The Angle of Attack control system is basically using the PID toolkit provided in the LabVIEW [15]. Figure 20 shows that the operator only needs to enter the desired set point of angle of attack and after that press the OK button then the system will move the motor up to the desired set point position or until it reached the desired angle of attack position.…”

and Space (LAPAN) has got a supersonic wind tunnel aimed at conducting research in high-speed motion object. In the past, the condition made the access on LAPAN's supersonic wind tunnel limited; which also made this device could only be used for the shockwave observation utilizing the schlieren apparatus. As a consequence, the data acquisition system could not collect data from sting balance; as some of the control panels were either a non-operational or in need of calibration. Based on these conditions, this research was conducted in order to develop a new integrated control system and data acquisition. Furthermore, the system was built based on the PXIe module from National Instrument and LabVIEW graphical programming which was used as the user interface, so that it could achieve the effectiveness of operation in terms of the time and the better data quality. In the recently developed system, the angle of attack (AoA) controlwhich was operated manually in the past-had been optimized into a digital control using a PID control method. As the AoA control had successfully become automated, there is a new testing option for moving the AoA; while the wind tunnel is running. In terms of data acquisition, the result after the optimization shows that it can collect better data (the noise /interference becomes smaller than the previous data), and now the data from the balance, the pressure data, the AoA position, and block position can be recorded.

“…The output value of the filter depends on the filter length and its weights. Although FIR filters are used to improve the quality of control and to reduce impact of signal noise, they might decrease the controller efficiency if used incorrectly [4,45]. This is due to the fact that filtration adds a side-effect-phase delay of the filtered signal.…”

,andrzej.przybyl}@iisi.pcz.pl Genetic programming algorithms and other population-based methods are a convenient tool for solving complex interdisciplinary problems. Their characteristic feature is that they flexibly adapt to the problem and expectations of a designer. In this paper, they are used for designing complex control systems. In particular, a new approach for automatic designing of PID-based controllers which are resistant to noises in the measuring path is proposed. It is based on the knowledge about an object model and capabilities of the genetic algorithm and genetic programming. Not only do these make it possible to tune parameters and select the structure of PID-based controllers, but they also tune parameters of some additional components of a complex controller structure, like parameters of finite impulse response (FIR) filters. The idea of the proposed approach relies on proper encoding of the controller and a dedicated way of evolutionary processing of encoded solutions. The approach proposed in this paper has been tested using a typical control problem, i.e. a DC motor control problem.
