In view of the mars reentry problem under external disturbance, this paper presents a guidance algorithm based on drag tracking. First of all, the reference drag is calculated based on the reentry model and the reference trajectory. Secondly, estimated disturbance via the sliding mode observer, this paper improve the accuracy of the controller parameters and increase the anti-disturbance capability...
In this paper Probabilistic Collocation Method (PCM) is introduced to solve a stochastic model representing wind farms in South Australia (SA). The model is based upon historical acquisition of wind source data, and considering the spatial correlation of wind speeds at neighboring wind farms. This correlation is used to reduce the number of uncertain parameters of the model, and then reducing the...
For the longitudinal dynamics of a highly maneuvarable missile, an enhanced sliding mode controller (SMC) based on nonlinear disturbance observer (NDO) is proposed. This scheme allows a continuous control robust to external disturbance and uncertain aerodynamic coefficients without the use of high control gain or extensive computational power. When the structure of whole control system is fixed, genetic...
