Unmanned helicopter control based on trim predication technology

This paper discusses the application of trim prediction technology which is used to design unmanned helicopter control laws. Trim prediction technology takes “implicit integrator” replace integrator appears explicitly in the PID control laws. For the first time, this paper adopts and applys the trim prediction technology to design unmanned helicopter control laws. According to simulation results, compared with traditional PID control laws, the simulation results are similar with PID control, but trim prediction technology can overcome disadvantages of traditional PID. The effectiveness of trim prediction control laws is documented through simulation. and shows that trim prediction technology can be used on unmanned helicopter.
