作为现代控制理论在工程设计上的具体应用,本文运用状态空间法研究一个实际的单通道控制驾驶仪系统。首先,对整个系统,包括作为控制对象的弹体,给出时域内的矢量——矩阵描述,从而建立系统的状态方程。弹轴座标系的状态方程表明,该系统是一个时变非线性反馈控制系统。应用代数等价定理,将时变系统变换为等价的定常系统。在此基础上,研究系统的稳定性条件,并对系统的整定方法加以简要讨论。
As a concrete application of modern control theory in engineering design, this paper uses state space method to study an actual single-channel piloted pilot system. First of all, we give the vector-matrix description in the time domain for the entire system, including the projectile as the control object, so as to establish the state equation of the system. The equation of state of the shaft coordinate system shows that the system is a time-varying nonlinear feedback control system. Using algebraic equivalence theorem, the time-varying system is transformed into an equivalent stationary system. On this basis, the stability conditions of the system are studied and the system tuning method is briefly discussed.
