The weighted output vector z consists of the following:
• Filtered inputs ( )
• Plant states (xp)
• Filtered plant outputs ( )
• Integrated, filtered plant outputs (yI)
The disturbance input vector (w) consists of the following:
• General LQG state disturbances (wx)
• General LQG output disturbances (wy)
• Input-referred disturbances or process noise (wp)
• Measurement, or sensor noise (ws)
• Filter noise (wF)
• Reference noise for the purpose of setpoint tracking (wr)
The measured output consists of the following:
• Integrated, filtered measured plant outputs (yI,sens)
• Filtered measured plant outputs ( )
• Measured plant outputs (yp,sens)
