[英]sensor resolution impact on dynamics
Is there a way to apply sensor model inside dynamics of a system in Matlab?有没有办法在 Matlab 的系统动力学中应用传感器 model?
Suppose dynamics of open loop system are:假设开环系统的动力学是:
xdot = A x + B u
y = c x + D u
x is 4 states (th1, th2, th1_dot, th2_dot)
. x 是 4 个状态
(th1, th2, th1_dot, th2_dot)
。 The open loop system is denoted by G_p
, and the control is denoted by G_c
.开环系统用
G_p
表示,控制用G_c
表示。 The closed loop system would be闭环系统将是
G_cl = Gp Gc/(1+Gp*Gc)
For now, I model sensor with floor
function in Matlab and after controlling the system and simulating the response of system to a given input, I quantize one of the states with floor function. For now, I model sensor with
floor
function in Matlab and after controlling the system and simulating the response of system to a given input, I quantize one of the states with floor function. But, since this does not give realistic impact of sensor on other states, I want to move sensor model inside my open loop dynamics or at least before the controller is implemented.但是,由于这不会对传感器对其他状态产生实际影响,我想将传感器 model 移动到我的开环动态范围内,或者至少在实现 controller 之前移动。
I appreciate any ideas.我很欣赏任何想法。
