Performance of particle swarm optimization under different range of direct current motor's moment of inertia / Mohd Azri Abdul Aziz

The implementation of Particle Swarm Optimization (PSO) algorithm in optimizing Proportional-Integral-Derivative (PID) controller's parameters is a popular technique to improve the performance of a control system. A prevalent application is a Direct Current (DC) motor control system with variations in parameters value have been used. Moment of inertia is one of the essential parameters of a DC motor which can affect the transient response including rise time, settling time, overshoot and steady state error. However, the use of moment of inertia and other parameters of DC motor are mostly to complete the transfer function and no specific analysis was done on the effects of their variations to the control method. This research investigates the effect of moment of inertia on the performance of PSO algorithm utilizing the Weighted Transient Response Index (WTPJ) based fitness function in optimizing PID controller parameters to control a DC motor. Five fitness functions were used in comparing the performance of PSO algorithm which includes Integral Absolute Error (IAE), Integral Time-weighted Absolute Error (ITAE), Integral Squared Error (ISE), Integral Time-weighted Squared Error (ITSE) and WTRI. For WTRI alone, several variations of weight combinations have been tested in determining their effects on the performance of PSO algorithm under different range of moment of inertia, from 3.88xl0"7 kgm2 to 3.88x10"1 kgm2 which is within a range found in literature. The experimental results shows that with a higher values of moment of inertia, WTRI based fitness function managed to outperform the other four error based fitness functions. It was also shown that a threshold for moment of inertia can be defined where the performance of PSO algorithm was affected only if the moment of inertia of the DC motor is more than the threshold value. The details exploration of WTRI based fitness function shows the significance of prioritized weight in Prioritize Single Non Zero (PSNZ) weight category towards its associated transient index was proven while for Prioritize All Non Zero (PANZ) weight category, the complex relationship between rise time, settling time and overshoot seems to interfere the ability of its prioritized weight in fully controls their associated transient response outputs

Machine vision based height measuring system

This paper presents a machine vision based height measuring system. The system will measure the height of a product based on the input from a webcam. The input image from the webcam will then be processed using image processing and then calculated to give the height of the product. In the market, there are many products that need to be measured whether the length or the height. These products also have different size and shape. There are several problems when using manual method for measuring such as man power will be needed at the station, longer time needed for measuring the product and the measurement may not be so accurate. This system aims to reduce these problems by developing a measuring system based on vision system

Inovasi produk "Smart Panel" sebagai kaedah penyelesaian masalah pembentangan hasil kerja pelajar (Smart Panel innovation as a problem solving method for student work's presentation) / Thuraiya Mohd … [et al.]

Proses pengajaran dan pembelajaran melibatkan beberapa aktiviti dan kaedah yang dilaksanakan secara berterusan ke arah menyediakan pendidikan komprehensif dan efektif. Proses pengajaran dan pembelajaran (PnP) ini perlu didokong dengan kemudahan fasiliti dan peralatan PnP yang efektif. Kekurangan fasiliti dan peralatan PnP mempengaruhi kualiti penyampaian dan juga proses pengajaran dan pembelajaran. Kekurangan fasiliti dan peralatan PnP ini turut menjejaskan rekabentuk kurikulum dan seterusnya memberikan kesan keatas pembentukan modal insan berkualiti yang mempunyai daya kreativiti dan cara pemikiran kritis. Justeru kajian ini, memfokus kepada masalah ketidakkeberkesanan proses PnP disebabkan kekurangan peralatan PnP iaitu panel pameran. Kajian ini mencadangkan inovasi kreatif serta inventif iaitu "smart panel" bagi menyelesaikan masalah yang wujud. Penemuan daripada kajian empirikal ini telah mendedahkan beberapa kelemahan dalam proses PnP yang menggunakan panel pameran sediada. Kelemahan yang signifikan adalah tempoh pembentangan yang lama dan seterusnya menghilangkan konsentrasi pelajar dan pensyarah. Keadaan ini telah menyebabkan masalah sampingan seperti terpaksa menyediakan slot pembentangan di waktu malam dan mewujudkan suasana yang tidak kondusif dalam studio. Oleh itu, inovasi "smart panel" telah dihasilkan bersesuaian dengan meja dan ruang studio sediada untuk menambah baik peralatan sediada dengan mengambilkira faktor masa, kos dan ruang semasa. "Smart Panel' ini adalah lebih efisien dan mudah untuk dikendalikan. Ujilari terhadap sistem ini menunjukkan masa pembentangan pelaj ar dapat disingkatkan daripada satu (1) j am (menggunakan panel biasa) kepada setengah (1/2) jam (menggunakan "smart panel"). Selain itu, ia dapat menjimatkan kos PnP. Justeru, diharap inovasi ini dapat diaplikasikan pada seluruh UiTM, malah organisasi lai

Caseous lymphadenitis in a goat

Despite the sero–positivity of caseous lymphadenitis (CLA) in Malaysian farms, cases with clinical signs of CLA are rarely encountered. An 8–month–old Saanen breed of goat was reported with a history of a subcutaneous mass beneath the jaw, on the right side. The consistency of the mass was non–movable, solid and hard on deep palpation. A tentative diagnosis of caseous lymphadenitis (CLA) was made based on the characteristic of the lesions presented and its contagious nature. The mass was incised and the purulent aspirate showed growth of Corynebacterium pseudotuberculosis on culture. Agar gel precipitation test (AGPT) was positive for Corynebacterium pseudotuberculosis. The mass was lanced and routine wound flushing resulted in recovery

Self-tuning fuzzy PID controller using online method in essential oil extraction process

During the extraction process, the temperature plays the major effect on the quality and output yield.Numerous studies on this domain mention that excessive heat during the extraction process will degrade the quality of oil and produced poor output.Recently, researchers take efforts to fix this problem by develop intelligent control technique in order to regulate the temperature. This study proposed the self-tuning fuzzy PID (STFPID) controller using online method. The STFPID controller will regulate the steam temperature below 100OC where very little publication so far discussed on that range.The robustness of STFPID controller was test using load disturbance and set point tracking.The performance effectiveness was evaluated based on rise time, settling time, percent overshoot, and steady stare error.From the simulation result, the STFPID controller shows good performance in both transient and steady state dynamics.The STFPID controller also has the ability to track the set point change and curb the load disturbance
