摘要
首先概述了直升机建模与仿真问题的发展。阐明了在精确的模型下进行仿真控制的必要性和可行性。依据直升机空气动力学,尽量不简化各影响因素,建立直升机的数学模型。分析并探讨了对如此高维、非线性、强耦合的系统进行控制,应当采取怎样的策略与方法。针对现有的直升机控制,提出了一些优化设想。仿真结果表明,该控制策略是基本成功的。
The development of modeling and simulation for helicopter is summarized first. The necessity and feasibility of Simulation with an exact helicopter model is demonstrated subsequently. The math- ematical model of helicopter is developed according to the helicopter aerodynamics with least simplification. Then, control strategies and methods for such a high-dimension, nonlinear, strongly coupled system are analyzed and discussed. Some control optimization concepts are proposed. The simulation results show that these strategies are generally successful.
