چکیده

In this paper, we use generalized incremental predictive control to stabilize attitude of satellite. We compare GPC with GIPC algorithm and present that GIPC has better performance. The three-axis attitude control systems are activated in pulse mode. Consequently, a modulation of the torque command is compelling in order to avoid high non-linear control action. This work considers the Pulse-Width Pulse-Frequency modulator is composed of a Schmitt trigger, a first order filter, and a feedback loop. PWPF modulator has several advantages over classical bang-bang controllers such as close to linear operation, high accuracy, and reduced propellant consumption. 与PWPF调制器卫星姿态控制中使用预测控制算法伊赫桑抽象在本文中，我们用广义增量预测控制，以稳定卫星姿态。我们比较GPC与GIPC算法，并提交GIPC具有更好的性能。三轴姿态控制系统在脉冲模式激活。因此，转矩指令的调制是为了避免高非线性控制动作引人注目。这个工作考虑了脉冲宽度脉冲频率调制器是由一个施密特触发器，一个一阶滤波器，以及一个反馈环路。 PWPF调制器拥有经典砰 - 砰控制器的优点很多，比如接近线性操作，精度高，并减少推进剂消耗。
