Double planes discrete variable structure tracking algorithm
With the development of aviation computer and aviation electronics technologies, the analog tracking algorithm has been unable to meet the need in project. But discrete variable structure tracking algorithm meets the requirement. After go into the sliding mode, the traditional discrete variable structure tracking algorithm will take place of buffeting, and will have phenomenon of the exhale when the front angel is big. In light of the above factors, in order to further improve the precision guided, the no buffeting discrete variable structure double planes tracking algorithm with a compensation of the disturbance is given. The simulation results show that the discrete signal guidance law can meet the tactical UCAV indicator.
