Lightweight quick response aerial remote sensing inertial-stabilized platform controlling system

Abstract

The invention discloses a lightweight quick response aerial remote sensing inertial-stabilized platform controlling system used for carrying out initiative controlling upon triaxial frames of stabilized platforms. The system comprises a DSP module, an FPGA module, a PWM power driving module, brushless DC torque motors, a stabilized platform frame, a measuring sensor, and an interface circuit. Angular position information, angular rate information and attitude information of the frame output by the measuring sensor are acquired by the DSP module and the FPGA module through the interface circuit in real time. PID controlling algorithm is executed by the DSP module and the FPGA module, and 18 PWM signals for controlling the three brushless DC torque motors are generated. The signals are converted into voltage signals by the PWM power driving module, and the brushless DC torque motors are driven, and the frame is driven to rotate, such that the initiative controlling upon the triaxial frame is realized. According to the invention, an independent mode and a combined mode are realized, and a frame soft lock function and an independent course configuration function under the combined mode are realized. Therefore, the operation of the platform is more reliable and intelligent.
