The study of the dynamic characteristics of two- and three-engine thyristor electric motors with constant current, in the case of a multi-motor control system, taking into account the elasticity of mechanical shafts are reviewed in this article. Such multimotor control systems are widely used in metallurgical production. For example, in sheet rolling mills, where in the mechanical part there are moments of significant dynamic curvature. The paper also reviews the functional and structural schemes of a cohesive multi-engine system. In the case of a multi-motor touring electric motor system, the structural scheme of a two-engine drive was studied in order to determine the correct load distribution. The study was conducted using a computer program - MATALAB using 150 kW and 300 kW engines. A Kalman filter-like observation device is used to quench the binding oscillations generated in the system. The quality indicators obtained from the transient mode studies are close to the optimal parameters, so the considered system is suitable for multi-motor rolling mills.

ABSTRAK Paper ini bertujuan untuk menganalisa rangkaian sistem kendali putaran motor menggunakan Silicon Controlled Rectifier (SCR) atau Thyristor. Eksperimen sistem kendali putaran motor ini menggunakan dua rangkaian yang berbeda. Rangkaian pertama menggunakan dua sumber, yaitu sumber tegangan DC 12 v terhubung dengan motor universal secara seri dengan resistor dan SCR, sedangkan sumber tegangan DC variabel 0 sampai 1.5 v dihubung paralel dengan kapasitor dan resistor. Rangkaian kedua menggunakan satu sumber tegangan AC 5 v yang dihubungkan dengan saklar dan motor. Pada rangkaian kedua ini motor dihubungkan dengan potensio, SCR, dioda serta kapasitor yang dipasang paralel dengan sumber tegangan AC. Hasil eksperimen menunjukkan dalam rangkaian menggunakan sumber tegangan DC, motor DC akan berputar saat saklar S1 tertutup. Kondisi motor akan berputar lebih cepat ketika sumber tegangan variabel diatur lebih besar dari 0 v sehingga arus gate Ig lebih bear dari 400 mA. Adapun Eksperimen dengan sumber tegangan AC, motor akan berputar dengan menambahkan dioda D3 dan pengaturan kecepatan melalui potensio meter Rv sampai posisi maksimum. Kata kunci: analisa, motor DC, SCR, sistem kendali ABSTRACT The objective of this study is to analyse the circuit of DC motor control system using Silicon Controlled Rectifier (SCR) or Thyristor. In this experiment the circuit of control system for the motor using two different circuits. The first circuit using two sources, the 12 v DC voltage is connected to universal motor and series with a resistor and SCR, while the DC variable voltage source of 0 to 1.5 v connected in parallel to the capacitor and resistor. The second circuit uses a single source of 5 V AC voltage connected to the switch and the motor. In the second circuit, the motor is connected to the potentio meter, SCR, diode and capacitor in parallel with the AC voltage source. The experimental results showed the circuit using a DC voltage source impacted the DC motor rotated after the switch S1 is closed then the motor rotated more faster when the variable voltage source is set greater than 0 v then the gate current Ig will be greater than 400 mA. The AC voltage source rotated the DC motor, when inserted the diode D3 to control the motor rotation using potentio meter. The motor can be stopped by minimising Rv.

Abstract The paper deals with an analysis of automatic control system with continuous and discrete PID controllers. A method of tuning the parameters of the continuous controller is presented, which is optimal according to the ITAE criterion. The behavior of control systems with discrete controllers whose parameters were tuned using the mentioned method are described. The impact of changes in the sampling period of controlled signal on the control quality is shown. Changes of the values of optimal parameters of discrete PID controllers in relation to changes of the sampling rate of controlled signal are characterized.

Currently, nonlinear pulse automatic control systems have become widespread, so there is a need to develop methods for their study. Pulse regulators are created on the basis of positional with the addition of pulse breakers. They can be represented as a non-linear element, a simple impulse element and a forming circle connected in series. The aim of the study was to determine the optimal parameters for setting up a relay-pulse controller for an astatic object with a delay. When determining the parameters of adjustment of the relay-pulse regulator for the quality indicator in the optimization of the automatic control system was taken as the total square deviation. Applying this criterion, the pulse duration of the regulator was determined. The time quantization interval is determined from the condition of ensuring the absolute stability of the automatic control system. Analytical dependences were obtained to determine the pulse duration and time quantization interval, which make it possible to determine the debugging parameters of the relay-pulse controller for a first-order astatic object with a delay. This ensures a minimum control error, and the control system is stable.
