Optimization of glide trajectory design: Proportion derivative controller simulation

According to the transmit function of the glide trajectory of the flight vehicle this paper designed a proportion derivative (PD) controller. This paper adopts the ITAE (Integral Time Absolute Error) method to optimize the PD parameters. During the process of optimization, the noise was considered in the derivative calculation. This paper eliminates the noise by using the first order filter. The result shows the noise is eliminated well and the group of PD controller parameters is calculated. It is from the ITAE method and they were sent to the single neural net PD controller. From the single neural net simulations, the result met the basic requirement. The parameters were also simulated in the glide trajectory by math simulations. The flight condition shows good agreement with the expectation law.
