It is based on sending ultrasonic waves through a specific medium and observing the returning echoes to measure the distance from the device to the Target. The system is implemented using PIC16F873 microcontroller because of its excellent data capturing features and accurate and fast analog-to-digital conversion ability.The system architecture of the Ultrasonic Range Meter is cost effective and has less power requirement with optimum performance. Apart from its application in medium scale fishing, It can be used in the areas of Robots, submarines, automobiles and in power lines protection system.

Due to the wide application of servomotors in many industrial processes, control of speed is a vital issue and has been of research interest for decades. This heuristic paper therefore presents performance analysis of Linear Quadratic Regulator controller and comparison of its time response matrices in open and closed loop model in servomotor speed control application. The aim is to show that the closed-loop servomotor has better speed control performance rather than its open-loop. It will be shown that Linear Quadratic Regulator method gives better performance, such as steady state error, settling time and overshoot. MatLab/Simulink software will be used to implement all simulations.

A controller designed with improved time-delay compensation and method of tuning has made it possible for speed control specifications to be optimally regulated for reliable performance. Servomotor speed control system has proven to exhibit several problems such as time lags due to analysis, measurement, transportation, computation and communication when using conventional controller. This problem leads to increased system dynamic error, decrease stability margin and affects system stability as evident in engineering and industrial process control. Therefore, this heuristic research focuses on hybridization of two controllers to remove inherent transcendental time delay from systems transfer function. This is a comparative study of two different controllers. From the simulation results, non-hybridise...
