Abstract

DC motors are widely used electronic components commonly found in everyday applications. Typically, when a load is applied, a DC motor tends to decelerate and fails to maintain a constant speed. To address this, motor speed can be controlled by adjusting the input voltage. However, to maintain consistent speed under varying loads, a control system is necessary. LQR works by adjusting the motor response to closely approach the desired setpoint, while minimizing both overshoot and undershoot within the system. On the other hand, LQT is a linear control strategy designed to ensure that the system output closely follows a time-varying reference or setpoint. When implemented, LQR yields a motor response that aligns with the target setpoint without any overshoot or undershoot. In contrast, if LQR is not applied, the motor response deviates significantly from the desired target and takes a longer time to settle. Meanwhile, the LQT method produces a quicker response reaching steady state in approximately ±0.5 seconds although it does introduce some overshoot and slight ripple in the signal. Despite these minor drawbacks, LQT is often favored over LQR for applications involving the MG-16B DC motor due to its superior speed in reaching the setpoint.

Abstract

A DC motor is commonly utilized as an actuator due to its ability to produce high torque. Controlling the motor's speed is one of the primary methods to manage its performance. Among various wireless communication options, radio waves are preferred since they do not require a clear line of sight between the transmitter and receiver. Employing multiple antennas offers benefits such as enhanced reliability and increased data transmission rates. This study focuses on designing and simulating four types of systems: SISO, SIMO, MISO, and MIMO. The performance of these configurations is evaluated and compared using Signal-to-Noise Ratio (SNR) and channel capacity, with variations in antenna count. Simulations were carried out in MATLAB to analyze how different antenna quantities (4, 8, and 16) affect channel capacity across an SNR range of 0 to 30 dB. The simulation outcomes reveal a substantial rise in system capacity, reaching up to 214 bits/Hz/sec when a 16x16 MIMO setup is applied at 30 dB SNR.

Abstract

This study explores the challenges of achieving precise positional control in three-phase AC motors, specifically in small industrial communities seeking to boost productivity with advanced motor systems. Although three-phase AC motors (0.25–1 kW) are efficient, they often face issues with control accuracy due to inherent inertia and long start-stop cycles. These motors typically take 1–2 seconds to reach full speed and 2–3 seconds to stop, causing disruptions in operations that require high precision and quick responses. To address these limitations, the research proposes an innovative control system designed to reduce startup time to 0.5 seconds and stopping time to 0.75 seconds. This system ensures precise positional halts, which is essential for applications such as automated production lines and specialized equipment like missile launchers. The control mechanism is fine-tuned for smooth synchronization with other subsystems, minimizing delays caused by slow motor responses. Tailored for small-scale industries, this solution tackles practical challenges by reducing downtime and improving accuracy in tasks that require short-duration actions. For example, it excels in rapid object tracking and locking, where delays could hinder target acquisition. By implementing this advanced motor control system in local industries, the research contributes to community empowerment, enhancing production efficiency, cutting operational delays, and fostering technological self-reliance. This approach highlights the transformative potential of modern motor control technology as a driver for industrial and economic growth, particularly in underserved regions where traditional systems are inadequate.
