This Publication has to be referred as: AbstractTemperature inversions represent an important element of air pollution in cities situated in natural valleys, such as the Sarajevo Valley. Due to the strong thermal stratification, which acts as a natural lid over the city, air circulation is blocked and pollutants accumulate and stay for much longer time. As a consequence, air pollution in the residential area of the city increases dramatically. Investigation of the temperature inversions in Sarajevo Valley was, for the first time, performed using unmanned aerial vehicles.

“…One more example of a pulsewidth modulator (PWM) application is a step controller for controlling an electric actuator with a constant speed of movement. The diagram of such a controller consists of a continuous PID controller, a differentiation element and a pulse-width modulator [1]. Application of PWM in an automatic controller provides efficient control of a thermal plant with high quality of the transient processes.…”

The results of the pulse-width modulation algorithms analysis are presented in the paper. The following two algorithms are analyzed: pulse-width modulator (PWM) based on the sawtooth waveform generator and PWM based on an integrator and a switch element. Mathematical formulae for designing the tuning parameters of PWM algorithms are presented. An improved PWM algorithm is suggested for a programmable logic controller (PLC) operating with integer variables without a filter of the input signal. The improved algorithm provides elimination of the influence of the input signal's noise on the PLC output signal. PLC output relay contact bouncing is eliminated by means of the improved algorithm. The reliability of PLC is improved and the operation time of PLC output relay contact is prolonged thanks to the improved PWM algorithm. The example of PWM application in an automatic controller for controlling a thermal plant is presented. The advantages of the improved PWM algorithm application are demonstrated. The technique for PWM pulses period defining with taking into account the dynamical properties of the controlled plant is presented.
