而针对大部分小型固定翼无人机而言,要想完整获取动力学模块,使用CFD或风动实验对整个代价是较高的。这里我们不考虑根据完整的被控对象模型去做解耦控制,采用一种基于能量法的高度-速度控制——总能量控制系统(TECS——Total Energy Control System)。 TECS 总能量控制系统 总能量原理 总能量控制系统最早(TECS)是在1...
首先是TECS(Total Energy Control System,总能量控制)算法相关的基础知识介绍。 总能量控制是运用能量控制与分配的方法,将速度控制与高度控制(切向加速度与纵向航迹角)进行解耦,用油门来控制总能量,用升降舵(俯仰角)来控制动能和势能之间的能量转换。 1. 总能量控制方法的公式推导。 飞机在垂直平面的运动方程为: 式...
The Total Energy Control System (TECS) was developed in the early eighties to overcome well known safety/design deficiencies of traditional Single Input/Single output (SISO) based Flight Guidance and Control (FG&C) systems. TECS uses generalized Multi Input/Multi Output (MIMO) based airplane ...
This paper describes some of the unique features of an integrated throttle-elevator control law known as the Total Energy Control System (TECS) which has been flight tested on NASA Langley's Transport Systems Research Vehicle. The TECS concept is designed around total energy principles. It utilizes...
The principle of TECS (total energy control system) control-law is applied to the control of lateral directional axis of aircraft, utilizing the combination of bias control and total energy decoupling. Rolling mode and yawing mode are decoupled, and the control system with zero steady-state error...

对这一问题,常规的解决思路是进行动力补偿,通过改变飞机推力实现轨迹控制。这是一种反区操纵技术,从能量的角度来看,动力补偿实质上是对飞机总能量的补偿,通过改变飞机的总能量实现轨迹不稳定情况下的轨迹控制。基于这样的思路,总能量控制(Total Energy Control System, TECS)方法,对于解决这一类问题更加具有优势。
