In order to improve the classification recognition rate, this paper carries out a theoretical analysis of the support vector machine (SVM), in order to find the optimal parameters C, g, the particle swarm algorithm optimized support vector machine (PSO-SVM) is introduced to carry out parameter optimization, and for the shortcomings of the PSO-SVM, the optimal classifier, i.e., Adaptive Particle Sw...Show More
The quadrotor dynamics model is established based on Newton’s motion theorem, and the adaptive fault observer is designed for the actuator fault. The attitude ring is based on the integral backstepping sliding mode to accurately track the desired attitude. The position ring considers the mass change to compensate through the designed adaptive law, and the position is controlled based on the adapti...Show More
In this paper, a sliding mode control algorithm based on variable mass estimation for quadrotor is studied. Firstly, based on the Newton Euler’s formula, a mathematical model of the variable-mass quadrotor is established. Secondly, an adaptive algorithm for variable quality estimation is presented and the estimated results are fed forward to control the attitude system. To obtain satisfactory traj...Show More
