DIDO utilizes trademarked expressions and objects [1] [2] that facilitate a user to quickly formulate and solve optimal control problems. [8] [17] [18] [19] Rapidity in formulation is achieved through a set of DIDO expressions which are based on variables commonly used in optimal control theory. [2]
H ∞ (i.e. "H-infinity") methods are used in control theory to synthesize controllers to achieve stabilization with guaranteed performance. To use H ∞ methods, a control designer expresses the control problem as a mathematical optimization problem and then finds the controller that solves this optimization.
LQR controllers possess inherent robustness with guaranteed gain and phase margin, [1] and they also are part of the solution to the LQG (linear–quadratic–Gaussian) problem. Like the LQR problem itself, the LQG problem is one of the most fundamental problems in control theory .
Variable Speed Fire Pump Controllers were invented and released with a UL Listing for fire pump service in 2003 by Master Control Systems, Inc. [1] [2] Paragraph 10.5.5 in the 2003 edition of NFPA-20 recognized Variable Speed as an accepted method for operating the fire pump. Then in the NFPA-20 2007 edition, section 10.10 was added to clarify ...
The company experienced a system issue that affected multiple products including account withdrawals, peer-to-peer payment service Venmo, online checkout and crypto. PayPal said the issue, which ...
The associated more difficult control problem leads to a similar optimal controller of which only the controller parameters are different. [5] It is possible to compute the expected value of the cost function for the optimal gains, as well as any other set of stable gains. [12] The LQG controller is also used to control perturbed non-linear ...
