This paper introduces a digital control system of gyroscope. The control circuit includes amplitude control loop, phase control loop and detection circuit. The amplitude control loop realizes the stability of driving mode vibration signal amplitude. The phase control loop consists of coarse phase locking loop and precise phase locking loop. At the initial stage, coarse phase locking is used to realize the rapid start-up of the gyroscope. Then after resonance frequency settles into the lock-in range of PLL, precise phase locking is used to realize the precise phase locking. The detection circuit realizes the output of gyro angular velocity signal. The design is implemented on PCB. The test results show that the scheme can realize the stable operation of gyroscope.

The article presents a model of a semiconductor compensator with an additional fuzzy control loop for the level of higher harmonics of the supply network current. The model was created and tested in the MATLAB 7.0.1 package. The dependences of the level of switching overvoltages, as well as the level of the amplitude of a single harmonic of the current of the supply network, on the relative voltage across the storage capacitor are investigated. The possibility of effective control of the amplitude level of a separate harmonic of the supply network current is shown. Graphical dependencies were obtained by means of modeling, their analysis was carried out, which confirmed the theoretical conclusions that must be taken into account when setting the parameters of a fuzzy controller. The use of an additional control loop for the level of a single harmonic makes it possible to adapt the proposed digital control system to varying conditions of the power system. The ability to adapt the pro-proponated digital control system in the energy system’s minus has been brought to the table, and the additional contour to regulate the level of the taken harmonic system has been added.
