Brushless Electric Motor Controllers for UAVs and Payloads

The electronics department of UVR LLC completed a cycle of works on adapting standard controllers of brushless electric motors to the features used in helicopter-type unmanned aerial vehicles.

Brushless motor controllers convert the DC voltage from batteries into a three-phase AC voltage, implement various motor control functions (modes of stabilization of the motor current, its rotation speed, etc.), adjusting the voltage and current supplied to the motor. The controllers are operated via CAN, UART interfaces and by means of a PWM signal.

The adapted controller type can be applied to UAV electric motors used for various purposes.

The UAV tail rotor motor controller is located in the motor module casing and represents a single structure with it. The controller software is adapted to the operation of the tail rotor with self-expanding blades. This controller is serially installed on the UAV “ELECTRON 7”.

Brushless Electric Motor Controllers for UAVs and Payloads

Till now the prototype of the UAV main rotor motor controller has been developed, adjusted and tested. On bench tests the long-term electric power of the controller has reached 3 kW.

Also, a brushless electric motor with this controller is used in the winch developed by UVR LLC. The software of this payload is adapted to the peculiarities of cargo lifting and lowering by the light UAVs.

New Application Options for the Radiation Monitoring System Based on the UAV “ELECTRON 7”

On February 16-17, 2023, St. Petersburg Electrotechnical University “LETI” hosted the International Practical Conference “Intelligent Border Checkpoint in Russia and the World: Competence-Based Approach to Creation” (IBCP 23).

As part of the forum, UE “ATOMTEX” (Minsk) presented a report “Mobile Radiation Scanning Systems”, in which it once again demonstrated to interested parties the mobile System for radiation reconnaissance and monitoring RMG-AT2000, developed jointly with UVR LLC, used with an unmanned helicopter “ELECTRON 7”.

The report reflects the main advantages of using the system. The possibility of airborne remote radiation monitoring of containers in temporary storage warehouses, vehicles in queues and trains can significantly increase the level of detection of gamma radiation sources, taking into account the fact that currently used radiation detection portals usually do not register radiation above the scanned object.

Improving the Quality of Control of the UVR UAVs by Using Simulation Analogues

UVR LLC specialists have taken another important step in improving the safety of testing and stability of helicopter-type unmanned aerial vehicles flights – their digital counterparts have been created. The models have been developed in a fairly short time and have already passed experimental verification while compared with piloted flights of prototypes.

These models are applicable both for operating prototypes of single-rotor helicopters with a tail rotor (gross weight up to 40 and 500 kg) and for coaxial configuration (gross weight up to 3,150 kg).

The models will allow conducting preliminary tests of aerial vehicles, determining and correcting their technical and dynamic characteristics, as well as setting acceptable parameters of control systems, which together will reduce the time and costs of testing, increasing the reliability and trustworthiness of the results.

Based on this approach, UVR LLC systematically continues the process of complex multi-parameter correction and improvement of engine control algorithms, pitch, roll, heading and height of the UAVs. At the same time, there is the possibility of an objective assessment for choosing a control loop scheme (either self-developed by UVR LLC, or a corrected ARDUPILOT scheme available in the public domain).

Virtual models can be used as simulators for comprehensive training, briefing, as well as for improving the skills of controlling aircraft of acting UAV operators.
