Electronic controller and unmanned aerial vehicle

The invention discloses an electronic controller for achieving electronic control over a turboprop engine. The electronic controller comprises a power board component, a CPU board component and an IOboard component; the power board component is used for input power conversion; the IO board component is connected with a sensor and an actuator of an engine separately, and used for conditioning signals input by the sensor into the signals that can be collected by the CPU board component, and driving the actuator of the engine based on control signals output from the CPU board component; the CPUboard component is used for signal collection, signal analysis and processing, and signal control; and the power board component is connected with the CPU board component and the IO board component separately, and the IO board component is connected with the CPU board component. According to the electronic controller, a hydromechanical control system is changed into a digital electronic control system, and the size and wei
