基于状态空间模型的无刷直流电机控制器设计

在无刷直流时机的位置伺服系统中，采用了基于状态空间模型的优化设计方法，综合出了次优控制器、建立了广义误差系统状态方程，并利用积分罚函数分段一经法处理伺服系统不等式约束的问题，得出了次优控制算法，经仿真证实，有杉该优化方法设计出的伺服系统的稳态跟踪误差为零；稳成输出不受阶跃干扰的影响；并具有期望的瞬态响应特性。

NEW DESIGN METHOD BASED ON THE STATE SPACE VARIABLE MODEL FOR THE CONTROLLER OF BRUSHLESS DC DRIVE

An optimal designing method based on the state space variable model for BLDC servo system is presented.The second rate optimal controller and a state equation with generalized spce error of the system are established.The second class optimal controlling algorithm is also obtained using integral penalty function piecewise linear method to deal with the restraint problem of the inequality for the servo system.It is shown by digital simulation that stationary tracing error using the optimal method to desgn servo system is zero. The step disturbance doesn't have influnce on stationary output.The servo systems have expected characteristic of instantaneous responses.
